I'm delighted happy to feature on the homepage of Die Zeit @diezeit.bsky.social today, for the first in a new feature of theirs, called "Just One Question", launching across print, online, audio, video, & newsletter www.zeit.de/wissen/2025-...

Sounds great. Are the talks recorded? (what is David silver talking about?)

I doom the concept of that 2021 Nature paper by showing how to compile any distributed quantum protocol into real-only gates while preserving locality.

Origins of the Ising model In 1925, Ernest Ising published a paper analyzing a model proposed in 1920 by Wilhelm Lenz for ferromagnetism. The model is composed of constituent units that take only two states and interact only wh...

A nice historical look at the origins of the Ising model.

Big grant news today! I feel very lucky and honored for this opportunity from @erc.europa.eu . We will attempt to go for a big qualitative step up in how we use AI/ML to predict how particles interact with matter. Stoked to get started on this in 2026. we will release job advertisements soon!

Artificial intelligence predicts future directions in quantum science – Physics World This podcast explains what happens when 66,000 research papers are used as training data

Can artificial intelligence predict future research directions in quantum science? Listen to this episode of the Physics World Weekly podcast to discover what is already possible. 🧪⚛️ ow.ly/SMZ150WRg5F

The researchers conducted an empirical study comparing an LLM to human programmers comprehending clean and confusing code.

Based on their analysis, both LLMs (via LLM perplexity) and humans (via EEG) are similarly confused about the code.

How do Humans and LLMs Process Confusing Code?

Hi, I am here! Will mostly post about Quantum Foundations/Computing and Quantum Music.

Unquestionable Bell theorem for interwoven frustrated down conversion processes In the Wang et al. paper "Violation of Bell inequality with unentangled photons'' [Science Advances, 1 Aug 2025 Vol 11, Issue 31], in which a brilliant experiment involving two interwoven frustrated d...

Thanks Ken, it's an interesting analysis and i am super happy that experts like yourself (or Marek/Jan-Ake's group yesterday arxiv.org/abs/2508.19207) are spending their time helping us clarify and improve the ideas. We are discussing your paper internally and will certainly come back to you.

Also, our experiment was covered in a video by @hossenfelder.bsky.social :

Super happy that experts look into this question and help us develop a better understanding of this strange nonlocal interference effect.

...leaves open loopholes for local-realistic models, it is possible to modify our measurement scheme, using a CH inequality, to get a 'unquestionable Bell theorem', and our experimental quality should already allow for its violation.

Super exciting paper by the groups of Jan-Åke Larsson & Marek Żukowski (two top-experts in Bell's theorem):
arxiv.org/abs/2508.19207

They analysed our recent paper on a very strange nonlocal interference effect (science.org/doi/10.1126/...).

They found that while the inequality we used ...

Busy Beaver Hunters Reach Numbers That Overwhelm Ordinary Math | Quanta Magazine The quest to find the longest-running simple computer program has identified a new champion. It’s physically impossible to write out the numbers involved using standard mathematical notation.

Last year, a team identified 47,176,870 as the fifth “busy beaver” number, a quantity tied to one of the hardest problems in computation. They've now found that the sixth number is so big, it's impossible to write without special notation. www.quantamagazine.org/busy-beaver-...

AI Comes Up with Bizarre Physics Experiments. But They Work. | Quanta Magazine Artificial intelligence software is designing novel experimental protocols that improve upon the work of human physicists, although the humans are still “doing a lot of baby-sitting.”

AI can improve the design of experiments. “It takes a lot to think this far outside of the accepted solution,” Adhikari said. “We really needed the AI.”

🚀 Excited to share our latest Review paper published in Nature Reviews Chemistry, exploring how machine learning (ML), when integrated with high-throughput experimental and computational data, can accelerate the discovery and design of heterogeneous catalysts.

Physicists disagree wildly on what quantum mechanics says about reality, Nature survey shows First major attempt to chart researchers’ views finds interpretations in conflict.

This year quantum physics turns 100, so @nature.com decided to conduct the biggest ever survey of what lies behind it. Do physicists really believe in multiple universes? Can influences happen instantaneously? Is the Copenhagen interpretation all it's cut out to be? ⚛️🧪 www.nature.com/articles/d41...
