I’m excited to share our most recent paper, published today in @Nature! This was a very fun and rewarding collaboration between @GoogleQuantumAI and @Stanford
Measurement plays a unique role in quantum mechanics. Publishing in @Nature in a collaboration between @GoogleQuantumAI and @Stanford, we explored how incorporating measurements could change the structure of information in space-time and lead to non-equilibrium phases. link ⬇️

Congratulations to this year’s Nobel Physics laureates — all 3 @UofCalifornia professors.
Home to groundbreaking physicists, including 2 immigrants leading the world in innovation and possibility, California is proud to dream big and deliver even bigger.
BREAKING NEWS
The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Physics to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”
New preprint: Learning measurement-induced phase transitions using attention proposes using QuAN, a quantum attention network to detect MIPTs without post-selection or classical sim.

Straight out of the dictator playbook: Trump warns that any protest against the wasteful military parade he’s throwing for his birthday will be crushed:
“They’re going to be met with very heavy force.”
Moronic own goal.
Some of these policies are legitimately indistinguishable from the answer to the thought exercise: “If I was president and wanted to destroy America’s competitive advantage, this is what I would do”
For everyone yelling about how this only exists on Reddit or for gender studies students. You’re wrong. I don’t know how to convince you of this, but listen to Francis Collins, one of the most respected scientists of his generation.
"Had Trump’s anti-foreign student policies been in place decades ago, Oxford grad Elon Musk would have built Tesla in the United Kingdom, Tsinghua University alum Jensen Huang would have built Nvidia in the People’s Republic of China or Taiwan, and Moscow State University grad Sergei Brin would have built Google in Russia."

One of the things that is bugging me about this whole “physics hasn’t done anything” line that people seem to be loving to justify the recent NSF cuts is that they don’t even realize the value of being trained as a physicist. Many of the top ML and AI advancements have been made with people from a physics background.
The obvious ones are Jared Kaplan and Dario Amodei (co-founders of Anthropic) but you also have people like Danilo Rezende and John Jumper (AlphaFold) who started out as physicists and are now deeply involved in AI research. Countless statistical physicists transition into ML theory as well and have made important contributions to scaling, ML stats, etc.
Even if you don’t care about what discoveries physicists have made in the past 75 years (they are still important: holography, superconductors, quantum information, etc.) you still very much ought to care about training physicists.
It’s not just an investment in pure sciences and laying the groundwork for academic work, it’s an investment in training smart people to solve hard problems which one day could translate to products you might use that could change your life for the better.
Even if you don't care one bit about scientific research, it's important to recognise the value of publicly funding people working on very hard problems and training bright young minds on how to solve them.
Do you think it’s a coincidence that so many successful entrepreneurs have a science background? The US didn’t become a global leader in technology and innovation by accident. It got there through decades of public investment in science, building research groups where young people could throw themselves at the toughest questions we face.
Today, 49% of US unicorn CEOs hold STEM degrees, and 70% of founding teams include at least one person with a STEM background. That pipeline of innovation was forged in universities and national labs, not in boardrooms
And when research is sustainably funded, the best international students come to US universities, and stay to build their companies (Elon Musk is one of them). Over 50% of international students in the U.S. are in STEM fields. Do you think this will continue if their research funding collapses by >70% and they can be kicked out at any time because the current government picks a fight with their University?
In the 21st century, attracting smart young people is the most valuable resource any nation can have today. In the future it will become even more critical. Scientific research is one of the strongest magnets for talent. You can ignore it, but the US is dismantling one of its most powerful engines of innovation
If you are interested in quantum computing, I strongly recommend this insightful article by @Caltech student @robbieking1000 calling for a "scrappier approach" to finding new applications.

This is truly amazing. The Deputy White House Press Secretary is claiming that I'm wrong, and that the "tariff rates" on Trump's chart were calculated by "literally" measuring every country's tariffs and non-tariff trade barriers.
To prove it, he screenshots the formula the USTR says was used to calculate the reciprocal tariffs we imposed on other countries. And when you back out the Greek symbols, what is that formula? Trade deficit/imports - exactly what I said it was.
I don't know if the Deputy Press Secretary was misinformed, or is just being misleading. Either way, the Trump administration did not "literally calculate tariff and non tariff barriers" to determine the tariff rates it's imposing on other countries. As I said, it divided our trade deficit with a country by our imports with that country, and then multiplied by 0.5 (because Trump was being "lenient").
Oh, and if our trade deficit/imports with a country is less than 10%, or we have a trade surplus with a country, Trump slapped a flat 10% tariff on that country.
