Google has a useful quantum algorithm that outperforms a supercomputer


An approach it calls “quantum echoes” takes 13,000 times longer on a supercomputer.

A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy, performing operations that would be effectively impossible to simulate on a classical computer. That claim didn’t hold up especially well, as mathematicians later developed methods to help classical computers catch up, leading the company to repeat the work on an improved processor.

While this back-and-forth was unfolding, the field became less focused on quantum supremacy and more on two additional measures of success. The first is quantum utility, in which a quantum computer performs computations that are useful in some practical way. The second is quantum advantage, in which a quantum system completes calculations in a fraction of the time it would take a typical computer. (IBM and a startup called Pasqual have published a useful discussion about what would be required to verifiably demonstrate a quantum advantage.)

Today, Google and a large collection of academic collaborators are publishing a paper describing a computational approach that demonstrates a quantum advantage compared to current algorithms—and may actually help us achieve something useful.

Out of time

Google’s latest effort centers on something it’s calling “quantum echoes.” The approach could be described as a series of operations on the hardware qubits that make up its machine. These qubits hold a single bit of quantum information in a superposition between two values, with probabilities of finding the qubit in one value or the other when it’s measured. Each qubit is entangled with its neighbors, allowing its probability to influence those of all the qubits around it. The operations that allow computation, called gates, are ways of manipulating these probabilities. Most current hardware, including Google’s, perform manipulations on one or two qubits at a time (termed one- and two-qubit gates, respectively.

For quantum echoes, the operations involved performing a set of two-qubit gates, altering the state of the system, and later performing the reverse set of gates. On its own, this would return the system to its original state. But for quantum echoes, Google inserts single-qubit gates performed with a randomized parameter. This alters the state of the system before the reverse operations take place, ensuring that the system won’t return to exactly where it started. That explains the “echoes” portion of the name: You’re sending an imperfect copy back toward where things began, much like an echo involves the imperfect reversal of sound waves.

That’s what the process looks like in terms of operations performed on the quantum hardware. But it’s probably more informative to think of it in terms of a quantum system’s behavior. As Google’s Tim O’Brien explained, “You evolve the system forward in time, then you apply a small butterfly perturbation, and then you evolve the system backward in time.” The forward evolution is the first set of two qubit gates, the small perturbation is the randomized one qubit gate, and the second set of two qubit gates is the equivalent of sending the system backward in time.

Because this is a quantum system, however, strange things happen. “On a quantum computer, these forward and backward evolutions, they interfere with each other,” O’Brien said. One way to think about that interference is in terms of probabilities. The system has multiple paths between its start point and the point of reflection—where it goes from evolving forward in time to evolving backward—and from that reflection point back to a final state. Each of those paths has a probability associated with it. And since we’re talking about quantum mechanics, those paths can interfere with each other, increasing some probabilities at the expense of others. That interference ultimately determines where the system ends up.

(Technically, these are termed “out of time order correlations,” or OTOCs. If you read the Nature paper describing this work, prepare to see that term a lot.)

Demonstrating advantage

So how do you turn quantum echoes into an algorithm? On its own, a single “echo” can’t tell you much about the system—the probabilities ensure that any two runs might show different behaviors. But if you repeat the operations multiple times, you can begin to understand the details of this quantum interference. And performing the operations on a quantum computer ensures that it’s easy to simply rerun the operations with different random one-qubit gates and get many instances of the initial and final states—and thus a sense of the probability distributions involved.

This is also where Google’s quantum advantage comes from. Everyone involved agrees that the precise behavior of a quantum echo of moderate complexity can be modeled using any leading supercomputer. But doing so is very time-consuming, so repeating those simulations a few times becomes unrealistic. The paper estimates that a measurement that took its quantum computer 2.1 hours to perform would take the Frontier supercomputer approximately 3.2 years. Unless someone devises a far better classical algorithm than what we have today, this represents a pretty solid quantum advantage.

But is it a useful algorithm? The repeated sampling can act a bit like the Monte Carlo sampling done to explore the behavior of a wide variety of physical systems. Typically, however, we don’t view algorithms as modeling the behavior of the underlying hardware they’re being run on; instead, they’re meant to model some other physical system we’re interested in. That’s where Google’s announcement stands apart from its earlier work—the company believes it has identified an interesting real-world physical system with behaviors that the quantum echoes can help us understand.

That system is a small molecule in a Nuclear Magnetic Resonance (NMR) machine. In a second draft paper being published on the arXiv later today, Google has collaborated with a large collection of NMR experts to explore that use.

From computers to molecules

NMR is based on the fact that the nucleus of every atom has a quantum property called spin. When nuclei are held near to each other, such as when they’re in the same molecule, these spins can influence one another. NMR uses magnetic fields and photons to manipulate these spins and can be used to infer structural details, like how far apart two given atoms are. But as molecules get larger, these spin networks can extend for greater distances and become increasingly complicated to model. So NMR has been limited to focusing on the interactions of relatively nearby spins.

For this work, though, the researchers figured out how to use an NMR machine to create the physical equivalent of a quantum echo in a molecule. The work involved synthesizing the molecule with a specific isotope of carbon (carbon-13) in a known location in the molecule. That isotope could be used as the source of a signal that propagates through the network of spins formed by the molecule’s atoms.

“The OTOC experiment is based on a many-body echo, in which polarization initially localized on a target spin migrates through the spin network, before a Hamiltonian-engineered time-reversal refocuses to the initial state,” the team wrote. “This refocusing is sensitive to perturbations on distant butterfly spins, which allows one to measure the extent of polarization propagation through the spin network.”

Naturally, something this complicated needed a catchy nickname. The team came up with TARDIS, or Time-Accurate Reversal of Dipolar InteractionS. While that name captures the “out of time order” aspect of OTOC, it’s simply a set of control pulses sent to the NMR sample that starts a perturbation of the molecule’s network of nuclear spins. A second set of pulses then reflects an echo back to the source.

The reflections that return are imperfect, with noise coming from two sources. The first is simply imperfections in the control sequence, a limitation of the NMR hardware. But the second is the influence of fluctuations happening in distant atoms along the spin network. These happen at a certain frequency at random, or the researchers could insert a fluctuation by targeting a specific part of the molecule with randomized control signals.

The influence of what’s going on in these distant spins could allow us to use quantum echoes to tease out structural information at greater distances than we currently do with NMR. But to do so, we need an accurate model of how the echoes will propagate through the molecule. And again, that’s difficult to do with classical computations. But it’s very much within the capabilities of quantum computing, which the paper demonstrates.

Where things stand

For now, the team stuck to demonstrations on very simple molecules, making this work mostly a proof of concept. But the researchers are optimistic that there are many ways the system could be used to extract structural information from molecules at distances that are currently unobtainable using NMR. They list a lot of potential upsides that should be explored in the discussion of the paper, and there are plenty of smart people who would love to find new ways of using their NMR machines, so the field is likely to figure out pretty quickly which of these approaches turns out to be practically useful.

The fact that the demonstrations were done with small molecules, however, means that the modeling run on the quantum computer could also have been done on classical hardware (it only required 15 hardware qubits). So Google is claiming both quantum advantage and quantum utility, but not at the same time. The sorts of complex, long-distance interactions that would be out of range of classical simulation are still a bit beyond the reach of the current quantum hardware. O’Brien estimated that the hardware’s fidelity would have to improve by a factor of three or four to model molecules that are beyond classical simulation.

The quantum advantage issue should also be seen as a work in progress. Google has collaborated with enough researchers at enough institutions that there’s unlikely to be a major improvement in algorithms that could allow classical computers to catch up. Until the community as a whole has some time to digest the announcement, though, we shouldn’t take that as a given.

The other issue is verifiability. Some quantum algorithms will produce results that can be easily verified on classical hardware—situations where it’s hard to calculate the right result but easy to confirm a correct answer. Quantum echoes isn’t one of those, so we’ll need another quantum computer to verify the behavior Google has described.

But Google told Ars nothing is up to the task yet. “No other quantum processor currently matches both the error rates and number of qubits of our system, so our quantum computer is the only one capable of doing this at present,” the company said. (For context, Google says that the algorithm was run on up to 65 qubits, but the chip has 105 qubits total.)

There’s a good chance that other companies would disagree with that contention, but it hasn’t been possible to ask them ahead of the paper’s release.

In any case, even if this claim proves controversial, Google’s Michel Devoret, a recent Nobel winner, hinted that we shouldn’t have long to wait for additional ones. “We have other algorithms in the pipeline, so we will hopefully see other interesting quantum algorithms,” Devoret said.

It’s troll vs. troll in Netflix’s Troll 2 trailer

Netflix’s international offerings include some entertaining Norwegian fare, such as the series Ragnarok (2020–2023), a surprisingly engaging reworking of Norse mythology brought into the 21st century that ran for three seasons. Another enjoyable offering was a 2022 monster movie called Troll, essentially a Norwegian take on the classic Godzilla formula. Netflix just dropped a trailer for the sequel, Troll 2, which looks to be very much in the same vein as its predecessor.

(Spoilers for the first Troll movie below.)

Don’t confuse the Netflix franchise with 2010’s Trollhunter, shot in the style of a found footage mockumentary. A group of college students sets off into the wilds of the fjordland to make a documentary about a suspected bear poacher named Hans. They discover that Hans is actually hunting down trolls and decide to document those endeavors instead, but soon realize they are very much out of their depth.

Writer/director André Øvredal infused Trollhunter with the driest of wit and myriad references to Norwegian culture, especially its folklore and fairy tales surrounding trolls. There are woodland trolls and mountain trolls, some with tails, some with multiple heads. They turn to stone when exposed to sunlight—which is why one of the troll hunters carries around a powerful UV lamp—and mostly eat rocks but can develop a taste for human flesh, and they can smell the blood of a Christian.

Directed by Roar Uthaug, the first Troll film is based on the same mythology. It had great action sequences and special effects and didn’t take itself too seriously. A young girl named Nora grows up with the mythology of Norwegian trolls turned to stone buried in the local mountains. An adult Nora (Ine Marie Wilmann), now a paleontologist, teams up with a government advisor, Andreas (Kim S. Falck-Jørgensen), and a military captain, Kris (Mads Sjøgård Pettersen), to take out a troll that has been rampaging across Norway, charting a path of destruction toward the heavily populated city of Oslo.

“Butt breathing” might soon be a real medical treatment

And Oxycyte was ideal for the group’s 2021 Ig Nobel-winning efforts. The experiments involved intra-anally administering oxygen gas or a liquid oxygenated perfluorocarbon to the unfortunate rodents and porcines. Yes, they gave the animals enemas. They then induced respiratory failure and evaluated the effectiveness of the intra-anal treatment. The result: Both treatments were pretty darned effective at staving off respiratory failure with no major complications.

So far, so good. The next logical step was to determine if EVA could work in human patients, too. “Patients with severe respiratory failure often need mechanical ventilation to survive, but these therapies can cause further lung injury,” the authors wrote in this latest paper. EVA “could give the lungs a chance to rest and heal.”

The team recruited 27 healthy adult men in Japan, each of whom received a dose of non-oxygenated perfluorodecalin via the anus. They were asked to retain the liquid for a full hour as the dosage slowly increased from 25 to 1,500 mL. Twenty of the men successfully completed the experiment. Apart from mild temporary abdominal bloating and discomfort—which proved to be dosage dependent and resolved with no need for medical attention—they experienced no adverse effects.

“This is the first human data and the results are limited solely to demonstrating the safety of the procedure and not its effectiveness,” said co-author Takanori Takebe of Cincinnati Children’s Hospital and the University of Osaka in Japan. “But now that we have established tolerance, the next step will be to evaluate how effective the process is for delivering oxygen to the bloodstream.”

Musk’s $1 trillion Tesla pay plan draws some protest ahead of likely approval

Ann Lipton, a University of Colorado Law School professor, told the Financial Times that she expects shareholders to approve the latest pay package despite the ISS recommendation. “They recommended against it before and the shareholders voted in favor, and this time Elon Musk gets to vote…  and his brother gets to vote,” she said. “That wasn’t true last time. I strongly expect that all of these proposals are going to go Tesla’s way.”

Pay plan goals are vaguely defined, letter says

The Musk pay plan was also opposed in a letter signed by the American Federation of Teachers; state treasurers from Nevada, Massachusetts, and New Mexico; and comptrollers from New York City and Maryland.

“We believe the Board’s failure to ensure CEO Musk devotes full attention to Tesla, while making him the highest-paid CEO in history, shows how beholden it is to management,” the letter said. “The Board has permitted Mr. Musk to be over-committed for years, allowing him to continue as CEO while taking time-consuming leadership roles at his other companies, xAI/X, SpaceX, Neuralink, and Boring Company.”

The letter said the pay plan’s vehicle-delivery goal could be reached even if annual sales decrease and that the Full Self-Driving subscription goal is “carefully worded to not actually require that the service ever achieves full unsupervised self-driving.”

The letter said the goal of delivering 1 million AI robots or “bots” is so vague that “even if Tesla fails to develop a commercially successful robot, it could market devices developed and manufactured by other firms and still achieve this milestone.” The robotaxi goal similarly “does not require that Tesla has designed and developed the robotaxis in question, nor that their operation be profitable,” the letter said.

The letter faulted the board for letting Musk take “a leadership position at the US Department of Government Efficiency (DOGE), a role widely seen as having a negative impact on the Company’s performance and brand… In our view, the Board’s failure to limit Mr. Musk’s outside endeavors while rewarding him with unprecedented pay packages for only a part-time commitment strongly indicates a lack of true independence by management and jeopardizes long-term shareholder value.”

F1 in Texas: Well, now the championship is exciting again

On Sunday, like in the sprint, Verstappen was unchallenged into turn 1 and drove to the checkered flag without much drama. Norris probably had the speed to challenge him, but the Ferrari of Charles Leclerc, which started the race on soft tires rather than mediums, used his grip advantage to pass Norris at the first turn. Within about four laps Leclerc’s tires had already given their best, allowing Verstappen to eke out a small lead.

What followed was a wonderfully exciting battle between Norris and Leclerc for second place. The drivers were on different strategies: Leclerc would switch to a medium after his soft tire, Norris would do the opposite. It took Norris a while to pass Leclerc the first time, with the McLaren driver trying the same cutback move at a number of corners without success before eventually succeeding.

But Leclerc stopped first, and when Norris made his tire change he yet again had to overtake Leclerc. This time Norris was much braver on the brakes into turn 12 to complete the move. Once in clean air, Norris was matching Verstappen’s speed, but the gap was too much to close down.

Verstappen’s win brings him to within 40 points of Piastri, with Norris just 14 points behind his teammate. And remember, there’s 25 points for a win—another non-finish for Piastri would be a disaster now. Should Verstappen manage to overtake both, he will have overcome the greatest points deficit in F1 history to do so.

History doesn’t repeat itself, but they do say it rhymes. And I’m hearing some of the same melodies as 2007, when dueling McLaren drivers took points off each other to allow Kimi Räikkönen and Ferrari to win the driver’s championship—and also 1986, when dueling Williams drivers lost to the McLaren of Alain Prost. If 2025 becomes Verstappen’s fifth world championship, it should go down as his most accomplished.

And there’s not long to wait: The next round takes place next weekend in Mexico City.

With deadline looming, 4 of 9 universities reject Trump’s “compact” to remake higher ed

Earlier this month, the Trump administration made nine elite universities an offer they couldn’t refuse: bring in more conservatives while shutting down “institutional units that purposefully punish, belittle, and even spark violence against conservative ideas,” give up control of admissions and hiring decisions, agree to “biological” definitions of sex and gender, don’t raise tuition for five years, clamp down on student protests, and stay institutionally “neutral” on current events. Do this and you won’t be cut off from “federal benefits,” which could include research funding, student loans, federal contracts, and even student and faculty immigration visas. Instead, you may gain “substantial and meaningful federal grants.”

But the universities are refusing. With the initial deadline of October 20 approaching, four of the nine universities—the University of Pennsylvania, Brown, University of Southern California, and MIT—that received the federal “compact” have announced that they will not sign it.

In addition, the American Council on Education, which represents more than 1,600 colleges and universities, today issued a statement calling for the compact to be completely withdrawn.

The compact would “impose unprecedented litmus tests on colleges and universities as a condition for receiving ill-defined ‘federal benefits’ related to funding and grants,” the statement says, and goes on to add that “it offers nothing less than government control of a university’s basic and necessary freedoms—the freedoms to decide who we teach, what we teach, and who teaches… The compact is just the kind of excessive federal overreach and regulation, to the detriment of state and local input and control, that this administration says it is against.”

nation-state-hackers-deliver-malware-from-“bulletproof”-blockchains

Nation-state hackers deliver malware from “bulletproof” blockchains

Hacking groups—at least one of which works on behalf of the North Korean government—have found a new and inexpensive way to distribute malware from “bulletproof” hosts: stashing them on public cryptocurrency blockchains.

In a Thursday post, members of the Google Threat Intelligence Group said the technique provides the hackers with their own “bulletproof” host, a term that describes cloud platforms that are largely immune from takedowns by law enforcement and pressure from security researchers. More traditionally, these hosts are located in countries without treaties agreeing to enforce criminal laws from the US and other nations. These services often charge hefty sums and cater to criminals spreading malware or peddling child sexual abuse material and wares sold in crime-based flea markets.

Next-gen, DIY hosting that can’t be tampered with

Since February, Google researchers have observed two groups turning to a newer technique to infect targets with credential stealers and other forms of malware. The method, known as EtherHiding, embeds the malware in smart contracts, which are essentially apps that reside on blockchains for Ethereum and other cryptocurrencies. Two or more parties then enter into an agreement spelled out in the contract. When certain conditions are met, the apps enforce the contract terms in a way that, at least theoretically, is immutable and independent of any central authority.

“In essence, EtherHiding represents a shift toward next-generation bulletproof hosting, where the inherent features of blockchain technology are repurposed for malicious ends,” Google researchers Blas Kojusner, Robert Wallace, and Joseph Dobson wrote. “This technique underscores the continuous evolution of cyber threats as attackers adapt and leverage new technologies to their advantage.”

There’s a wide array of advantages to EtherHiding over more traditional means of delivering malware, which besides bulletproof hosting include leveraging compromised servers.

    • The decentralization prevents takedowns of the malicious smart contracts because the mechanisms in the blockchains bar the removal of all such contracts.
    • Similarly, the immutability of the contracts prevents the removal or tampering with the malware by anyone.
    • Transactions on Ethereum and several other blockchains are effectively anonymous, protecting the hackers’ identities.
    • Retrieval of malware from the contracts leaves no trace of the access in event logs, providing stealth
    • The attackers can update malicious payloads at anytime

Google will let Gemini schedule meetings for you in Gmail

Meetings can be a real drain on productivity, but a new Gmail feature might at least cut down on the time you spend scheduling them. The company has announced “Help Me Schedule” is coming to Gmail, leveraging Gemini AI to recognize when you want to schedule a meeting and offering possible meeting times for the email recipient to choose.

The new meeting feature is reminiscent of Magic Cue on Google’s latest Pixel phones. As you type emails, Gmail will be able to recognize when you are planning a meeting. A Help Me Schedule button will appear in the toolbar. Upon clicking, Google’s AI will swing into action and find possible meeting times that match the context of your message and are available in your calendar.

When you engage with Help me schedule, the AI generates an in-line meeting widget for your message. The recipient can select the time that works for them, and that’s it—the meeting is scheduled for both parties. What about meetings with more than one invitee? Google says the feature won’t support groups at launch.

Google has been on a Gemini-fueled tear lately, expanding access to AI features across a range of products. The company’s nano banana image model is coming to multiple products, and the Veo video model is popping up in Photos and YouTube. Gemini has also rolled out to Google Home to offer AI-assisted notifications and activity summaries.

Trade Escalation, Supply Chain Vulnerabilities and Rare Earth Metals

What is going on with, and what should we do about, the Chinese declaring extraterritorial exports controls on rare earth metals, which threaten to go way beyond semiconductors and also beyond rare earths into things like lithium and also antitrust investigations?

China also took other actions well beyond only rare Earths, including going after Qualcomm, lithium and everything else that seemed like it might hurt, as if they are confident that a cornered Trump will fold and they believe they have escalation dominance and are willing to use it.

China now has issued reassurances that it will allow all civilian uses of rare earths and not to worry, but it seems obvious that America cannot accept a Chinese declaration of extraterritorial control over entire world supply chains, even if China swears it will only narrowly use that power. In response, Trump has threatened massive tariffs and cancelled our APAC meeting with China, while also trying to calm the markets rattled by the prospect of massive tariffs and the cancellation of the meeting with China.

World geopolitics and America-China relations are not areas where I am an expert, so all of this could be highly misguided, but I’m going to do my best to understand it all.

There are some claiming this is in response to a new BIS ‘50% rule’ where majority owned subsidiaries are now subject to the same trade restrictions as their primary owners, or that this and other actions on America’s side ‘broke the truce.’

I acknowledge that ownership can get complex and thus this can impose non-trivial costs and cause some amount of risk mitigating action, but I don’t buy it as a central cause. It never made sense that we’d refuse to trade with [X] but would trade with [X]’s majority owned subsidiary, and imposing full extraterritoriality on 0.1% value adds plus taking other steps is not remotely proportionate retaliation for that, especially without any sort of loud warning. If that’s the stated justification, then it’s for something they were looking to do anyway.

If you buy the most pro-China argument being made here (which I don’t), that Lutnik and others ‘went rogue’ and did the 50% rule and other things behind Trump’s back to ‘get tough’ or sabotage the talks, thus making us untrustworthy, then the Chinese response seems quite unstrategic to me.

Whereas the right move if this did happen would have been to loudly call out the moves as having been done behind his back and give Trump a chance to look good, and only retaliate later if that fails. And even if China did feel the need to retaliate, the audacity of what China is trying to do is well beyond a reasonable countermove.

SemiAnalysis offers their thoughts on the rare earth portion and does not think they are aiming at a widespread supply chain cutoff.

Brad Setser views this as a maximum pressure strategy to try and get it all, as in full tariff rollback, rollback of export controls, even relaxation of national security reviews on Chinese investments. They’re laying many of their most powerful asymmetric cards on the table, perhaps most of them. That does seem like what is going on?

The export controls on chips presumably aren’t China’s primary goal here in any case. I assume they mostly want tariff relief, this is a reasonable thing to want, and on that we should be willing to negotiate. They get to play this card once before we (I hope) get our own production house in order on this, the card was losing power over time already, they played it, that’s that.

The initial response from Trump was to plan not to meet Xi at APAC and to threaten massive new tariffs, now that China is no longer ‘lying in wait’ after six months of what he claims were ‘good relations with China,’ hence the question we are now about to answer of what bad relations with China might look like, yikes. He says ‘things that were routine are no longer routine at all,’ which might be the best way to sum up the entire 2025 Trump experience.

Also, 30 minutes before Trump made the tariff announcement, someone opened an account on that day, created a Bitcoin short and closed with $88 million in profit. It’s 2025, you can just trade things.

That threat was always going to be part of the initial reaction, and thus does not itself provide strong evidence that China overreached, although the exact degree of how genuinely pissed off he would be was unpredictable, and this does seem to be on the upper end of plausible degrees of pissed.

The question is what happens next. China’s move effectively bets that China holds all the cards, and on TACO, that they can escalate to de-escalate and get concessions, and that Trump will fold and give them a ‘great deal.’

We are launching a $1 billion Pentagon buying spree to stockpile critical minerals, which we should have presumably done a long time ago given the ratio of the cost of a stockpile versus the strategic risk of being caught without, especially in an actual war.

We also are announcing this:

First Squawk: BESSENT ON SUPPLY CHAINS, RARE EARTHS: GOING TO DO EQUIVALENT OF OPERATION WARP SPEED TO TACKLE PROCESSING.

I am excited to do the equivalent of by far the most successful government program of the past decade and Trump’s greatest success.

America then, as is Trump’s common pattern, looked to show signs of desire for de-escalation, as Trump tries to calm the markets (which are down in Asia as well), and both nations express privately they want to reduce tensions. No one actually wants a big trade war and both sides have escalated to de-escalate. So Trump is both making big threats and sending out the message that everything is fine. He’s repeating that America is prepared to retaliate if China doesn’t back down, and is going to demand full rescinding of the rare-earth export rule.

China quickly attempted to walk back the implications and indicate intention to de-escalate, saying that the ban is only for military purposes and civilian uses will be approved, all you have to do is get all the Chinese licenses, as in acknowledge Chinese extraterritorial jurisdiction and turn over lots of detail about what you’re doing, and hope they don’t alter the deal any further. No need to worry.

Rush Doshi interprets these same recent PRC Ministry of Commerce public remarks as Beijing being ‘a little rattled’ and worried about global reaction, and declining to respond to Trump’s threats yet, but resolved to keep their new rare earths regime.

Rush Doshi: Bottom Line: Trump wants this regime withdrawn. Beijing won’t do that, but is trying to reassure it won’t implement it punitively. Obviously, that is not a credible promise on Beijing’s part, and US and PRC positions are at odds.

Beijing is emphasizing that this is ‘not a ban’ except for military use. Thinking this is what needs to be emphasized indicates they misunderstand the dynamics involved. This was not something that was misunderstood.

Perhaps it was intended as a warning that they could have done a ban and chose not to? Except that implicit threat is exactly the most unacceptable aspect of all this.

The argument that others need not worry does not hold water. Any reasonable business would worry. As for governments, you can’t be permitted by others to remain the sole supplier of vital military supplies if you don’t let them go into others military equipment, even if the rules are only ever enforced as announced.

Nor is America going to let China demand unlimited information transfer about everything that touches their rare earths, or accept China having a legal veto point over the entire global supply chain even if they pledge to only use it for military applications.

As in, this is not merely ‘Trump wants this regime withdrawn.’ This is an unacceptable, dealbreaker-level escalation that America cannot reasonably accept.

So we are at an impasse that has to give way in some fashion, or this escalates again.

I agree with Saif Khan and Dean Ball that we absolutely should not negotiate on our chip export controls, indeed given this move we should tighten them, especially on wagers and other manufacturing components.

We must use this as an impetus to finally pay the subsidies and give the waivers needed and do whatever else we need to do, in order to get rare earth production and refining in the West.

It’s not like all the deposits happen to be in China. America used to be the top producer and could be again. I strongly agree with Dean that we should (among other things) Declare Defense Production Act as needed on this one, as this is a key strategic vulnerability that we can and must fix quickly. As Dean points out, and economists always say, supply in the medium term is almost always more elastic than you think.

Note the justification China used for this new restriction, which is that any chip below 14nm or 256 layer memory has ‘military applications.’ Well then, where should we put the limit on our chip sales to them? They certainly have military applications.

Rush Doshi initially predicted financial sanctions from America may follow, which would solidify this as a very serious escalation all around if it came to that. Presumably such an escalation is unlikely, but possible.

The way this is playing out now does update us towards China having miscalculated and overplayed their hand, potentially quite badly if they are unable to offer an acceptable compromise while saving face and dealing with internal pressures.

Asserting control over supply and terms of trade is a trick you hopefully can only pull once. Demonstrate you have the world over a barrel because no one else was willing to pay a modest price to secure alternative supplies, and everyone is going to go pay a modest price to secure alternative supplies, not only of this but of everything else too, and look hard at any potential choke points.

That dynamic is indeed also one of the big problems with Trump’s tariff shenanigans. If you prove yourself willing to use leverage and an unreliable trading partner (provoked, fairly or otherwise) then everyone is going to look to take away your leverage and stop depending on you. Hold up problems that get exploited get solved.

In this sense, the response must inevitably go well beyond rare earths, even if a deal is reached and both sides back down.

Dean Ball: We should not miss the fundamental point on rare earths: China has crafted a policy that gives it the power to forbid any country on Earth from participating in the modern economy.

They can do this because they diligently built industrial capacity no one else had the fortitude to build. They were willing to tolerate costs—financial and environmental and otherwise—to do it.

Now the rest of the world must do the same.

China has created an opportunity of tremendous proportions for all countries that care about controlling their destiny: the opportunity to rebuild.

Every non-Chinese infrastructure investment, sovereign wealth, and public pension fund; every corporation that depends on rare earths; and every government can play a role.

This is an opportunity not just for the US, but for every country on Earth that wants to control its destiny. Together, we can build a new supply chain designed to withstand unilateral weaponization by a single country—one spread throughout the world.

Always remember that supply is elastic. If our lives depend on it, we can surmount many challenges far faster than the policy planners in Beijing, Brussels, and Washington realize.

Ben Thompson echoes similar points, that America gave the rare earth mining industry away by letting the Nuclear Regulatory Commission classify waste as nuclear, thus skyrocketing costs (so a fully pointless self-own, the same as on nuclear power) followed by letting the Chinese buy out what was left of our operations. We could absolutely get back in this game quickly if we decided we wanted to do that.

Peter Harrell goes into why getting American or friendshored production going is hard. Permitting and lawsuits make mining in America difficult (read: borderline impossible), it’s hard to get politics going for things that don’t come online for years, and profitability is rough without purchase and price guarantees.

That is very hard under our current equilibria, but is eminently solvable given political will. You can overcome the permitting. You can pass reforms that bypass or greatly mitigate the lawsuits. You can use advance market commitments to lock in profitability. The strategic value greatly exceeds the associated costs. If you care enough.

What about the parallel with advanced AI chips themselves, you ask? Isn’t that the same thing in reverse? There are some similarities, but no. That is aimed squarely at only a few geopolitical rivals, contained to one particular technology that happens to be the most advanced and difficult to duplicate on Earth, and one that China is already going full speed ahead to get domestically, and where share of global chip supply is a key determinant of the future.

Yes, there are elements of ‘China doesn’t get to do extraterritorial controls on strategic resources, only America gets to do extraterritorial controls on strategic resources.’ And indeed, to an extent that is exactly our position, and it isn’t new, and it’s not the kind of thing you give up in such a spot.

We also should consider the possibility that China’s economy may not be going well and they could feel backed into various corners, including internal pressures. Authoritarian states with central planning can often do impressive looking things, such as China going on history’s largest real estate building binge or its focus on hypercompetitive manufacturing and technology sectors, hiding the ways it is unsustainable or wasteful for quite a long time.

China has a huge slow moving demographic problem and youth that are by all reports struggling, which is both a crisis and indicates that many things are deeply wrong, mounting debt and a large collapsed real estate sector.

Recently China started clamping down on ‘negative emotional contagion’ on social media. Tyler Cowen suggests this shows wisdom but I would instead suggest the primary thing to observe is that this is not what you do when things are going well. It only makes the vibe more creepily dystopian and forces everyone’s maps to diverge even more from reality. It reflects and creates increasing tail risk.

I would presume the default outcome is that a detente of some form is reached before massive escalations actually get implemented. The market is concerned but not freaking out, and this seems correct.

There is still a lot of risk in the room. When cards like this are put on the table, even with relatively conservative negotiation styles, they sometimes get played, and there could end up being a fundamental incompatibility, internal pressures and issues of loss of face here that when combined leave no ZOPA (zone of possible agreement), or don’t open up one without more market turbulence first. I would not relax.

Is there risk that America could fold here and give up things it would be highly unwise to give up? Not zero, and when powerful cards like this get played it is typical that one must make concessions somewhere, but I expect us to be able to limit this to places where compromise is acceptable, such as tariffs, where our position was always in large part a negotiating tactic. If anything, this move by China only emphasizes the importance of not compromising on key strategic assets like AI chips, and tightening our grip especially on the manufacturing equipment and component sides.

Even if we end up making substantial concessions on tariffs and other negotiable fronts, in places China sensibly finds valuable, this whole exchange will still be a win. This was a powerful card, it is much harder to play it again, and we are going to make much stronger efforts than before to shore up this and other strategic weaknesses. If this causes us to take a variety of similar vulnerabilities properly seriously, we will have come out far ahead. While in general, I strongly dislike industrial policy, inputs that create holdup problems and other narrow but vital strategic resources can provide a clear exception. We should still strive to let markets handle it, with our main goal being to pay providers sufficiently and to remove restrictions on production.

Layoffs, a “coding error,” chaos: Trump admin ravages the health dept.

Federal health agencies are reeling from mass layoffs on Friday that appear to have particularly devastated the Centers for Disease Control and Prevention, despite some terminations being rescinded on Saturday.

Numbers are still sketchy, but reports from Friday indicate that more than 4,000 federal workers overall were initially targeted for layoffs. The Trump administration linked the firings to the ongoing government shutdown, which legal experts have suggested is illegal. Unions representing federal workers have already filed a lawsuit challenging the move.

Of the reported 4,000 terminations, about 1,100 to 1,200 were among employees in the Department of Health and Human Services (HHS). HHS is a massive department that houses critical federal agencies, including the Centers for Disease Control and Prevention, the National Institutes of Health, the Food and Drug Administration, and the Centers for Medicare & Medicaid Services, among others. Before Trump’s second term, the HHS workforce was about 82,000, but that was slashed to about 62,000 earlier this year amid initial cuts and efforts to push civil servants out.

While it’s unclear where all the new cuts occurred, reports from anonymous and external sources describe a major gutting of the CDC, an agency that has already been severely wounded, losing significant numbers this year. Its former leaders have accused the Trump administration of censoring its scientific work. It suffered a dramatic ousting of its Senate-confirmed director in August. And it was the target of a gunman weeks earlier, who shot over 500 rounds at its employees, killing a local police officer.

As terminations went out Friday, reports indicated that the terminations hit staff who produce the CDC’s esteemed journal Morbidity and Mortality Weekly Report, employees responding to the measles outbreaks in the US, others responding to the Ebola outbreak in the Democratic Republic of the Congo, workers in the Global Health Center, and disease detectives in the Epidemic Intelligence Service.

why-doesn’t-cards-against-humanity-print-its-game-in-the-us?-it’s-complicated.

Why doesn’t Cards Against Humanity print its game in the US? It’s complicated.

Or take Meredith Placko, the CEO of Steve Jackson Games, which produces games like Munchkin. “Some people ask, ‘Why not manufacture in the US?’ I wish we could,” she wrote. “But the infrastructure to support full-scale board game production—specialty dice making, die-cutting, custom plastic and wood components—doesn’t meaningfully exist here yet. I’ve gotten quotes. I’ve talked to factories. Even when the willingness is there, the equipment, labor, and timelines simply aren’t.”

But surely, you say, a box of cards should be possible. And it is. But CAH tells me that the downsides of US manufacturing for its game are still significant.

“We actually tried diversifying our suppliers by working with a US factory several years ago, but they were twice as expensive, three times slower, and much lower quality—something like 20 percent of games were unsellable due to production errors,” said a spokesperson for the company.

And although it is possible to print card games in the US, CAH makes other products too and would prefer to work with a single manufacturer who can handle all of it. Newer CAH games like Head Trip use “wooden tokens and a round folding board,” while another title called Tales “has a bound book and 20 tiny matchboxes of prompts.”

In the end, though, it’s not just about dollars and sense. It’s also about relationships and trust. CAH has “used the same factory in China since 2010, and they’ve grown alongside us from a small business to a huge operation,” I was told. “They do great work, we like them, and we feel a moral obligation to stand by them through Trump’s insanity.”

(If you want to produce Cards Against Humanity in the US, however, you can always download the free files for the game [PDF] and print it yourself. Be warned that it is quite vulgar!)

Board and card games are not one of the major pillars of the US economy, of course, but looking into how complicated it can be to get a game made does illuminate complex issues around globalization and manufacturing that are too often turned into simple soundbites.

Trump admin fires more health employees amid government shutdown

Questionable cull

Today’s layoffs are the work of White House Budget Director Russell Vought, a lead creator of the Project 2025 playbook, which planned a massive reduction in the federal workforce. In a post on X earlier today, Vought announced that the terminations “have begun.”

But as The Washington Post has previously reported, senior government officials have warned that Vought’s layoffs amid a shutdown are likely illegal, running afoul of the Antideficiency Act. The law forbids the government from incurring new expenses during a shutdown, and the process of laying employees off—which includes severance packages—does just that.

Federal employment lawyers told the Post that the move is almost certainly illegal for a second reason: Under federal regulations, a shutdown-driven lapse in funding does not count as one of the reasons federal employees can be terminated.

Last week, the American Federation of Government Employees and other unions representing federal workers filed a lawsuit over threats that the Trump administration would try to lay off workers during the shutdown.

In a statement today, AFGE National President Everett Kelley said, “It is disgraceful that the Trump administration has used the government shutdown as an excuse to illegally fire thousands of workers who provide critical services to communities across the country.”

“AFGE is currently challenging President Trump’s illegal, unprecedented abuse of power, and we will not stop fighting until every reduction-in-force notice is rescinded,” Kelley said.
