What paper / song pairing would you recommend for this Christmas? Here's our choice: "Random purification channel made simple" arxiv.org/abs/2511.23451 with "And he shall purify" from Handel's Messiah www.youtube.com/watch?v=_Ddy...

2025 Headline of the Year nominee (July)

Awful for academics but great news for Borges fans

Who knew that one day scientists would consider moving to Germany to escape fascism! 14 two-year postdoc positions in Germany in a new "Early Career Rescue Fellowship" scheme.

The semester is finally over, so it's time for me to post the memes my students made for extra credit on their final (Physics 438b: Quantum Mechanics). As always, good memes are the result of my inspiring teaching, bad memes are the result of kids these days. Let's start it off!

And the results of the annual Quantum Physics 2 meme competition are in… 🥁 🪘🛢️🍗 in fifth place we have a meme that I secretly have a lot of sympathy for…

Prof trying to hide from students.

Winners of the #FOCS2025 Cartoon Caption Contest: - "This guy is about to blow up the polynomial hierarchy." [ Rachel Zhang ] - "Not exactly what I meant by 'increase FOCS acceptance rate.'" [ @mahdi.ch ]

When you need to look fresh for a 9am meeting.

When a joke turns into a billion dollar industry.

Great initiative! But as a quantum computing startup Dulwich would never run other people's metrics. What if we don't come out at the top? It's safer to stick to our own metric, namely the largest number of qubits encoded in acorns stored in a wooden box!

"Our study demonstrates that [probabilistic] computers, implementing state-of-the-art replica-based Monte Carlo algorithms, can achieve a comparable, and in some cases more favorable, performance scaling on the same 3D spin glass problems." doi.org/10.1038/s414...

Since I might have to declare this account in my next ESTA application when I go to a conference in the US, let me preemptively say that I feel nothing but admiration towards the glorious leader and great father of all Americans, Donald J. Trump! Most humble of all men who have walked this Earth...

Sergey Frolov (@spinespresso.bsky.social) explains the disconnect between science and PR in quantum computing. The whole talk is worth a watch (it's on reproducibility issues in experimental condensed matter physics, including the infamous majorana zero modes). www.youtube.com/watch?v=_3t0...

"A single person claims to have authored 113 academic papers on artificial intelligence this year, 89 of which will be presented this week at one of the world’s leading conference on AI and machine learning," www.theguardian.com/technology/2...

We are on a brink of an unprecedented revolution in science that will change forever how science is done and what it means to be a scientist! Instead of having to do all our writing, reading and thinking ourselves, we will now be able to spend all our time on debunking wrong AI-generated papers!

Looking forward to #QIP2026!

so whats the next insane bubble, "quantum"?

We are in the era of Science Slop! (and it's exciting): open.substack.com/pub/superpos...

We've all been there during our undergrad. www.theguardian.com/us-news/2025...

Me attending a workshop in Paris.

Bold prediction: the current AI boom will be net negative for science simply because many scientists won't be able to afford to buy new computers. "Mainstream DDR5 memory modules now cost at least twice what they did in mid-2025." www.xda-developers.com/dram-prices-...

This is how you do research in a group of 3 these days: * person 1: provides a high level idea * person 2: does calculation on the board * person 3: checks vibes with ChatGPT

Love it when somebody joins Bluesky and the first thing they do is follow Dulwich.

Why is it that people who study entanglement are often twins?

Logical qubits politely requesting that you measure the correct ancillas in your syndrome extraction round

So excutives from Dwave and IONQ have recently dumped large amounts of stock. Zapata (kinda?) went bust... what are the other quantum computing stocks to watch?

D-Wave CEO and CFO dump $29 million worth of shares of their own company. Quantum pump and dump in action! www.newscase.com/d-wave-quant...

Did anyone notice that a quantum algorithms book dropped this year? doi.org/10.1017/9781... It's based on this paper: arxiv.org/abs/2310.03011

Well, I'm confident.

The other half of the quote is pretty crucial to the point:

Truth hurts. scottaaronson.blog?p=9344

Student: "I know these slides are AI-generated, I know that everyone in this meeting knows these slides are AI-generated, I would rather you just scrap these slides. I do not want to be taught by GPT." www.theguardian.com/education/20... Tech bro: But what if we upgraded our AI to quantum AI?

If you add a "q" in your surname, you become a quantum startup!

Can't wait to be able to simulate a NISQ computer on a fault-tolerant one!

Going through my checklist of what quantum computing companies have promised so far: ✔️ cure disease ✔️ solve climate change ✔️ solve food insecurity Also, you often hear that quantum will improve AI, which in turn is supposed to speed up solving everything that AI has been promised to solve.

Me with Hagoromo chalk.

2025 is officially the year of "vibe coding". www.bbc.com/news/article...

Not sure what to wear tomorrow? Use shallow quantum circuits to decide this! They "can accurately reproduce the short-horizon dynamics of discrete-time Markov chains derived from fashion electronic-commerce recommendation links". arxiv.org/abs/2511.08200

Even quantum CEOs are better at this. futurism.com/artificial-i...

Can I call them quantum panini relative entropies instead of sandwiched?

A recent @nature.com article claims that classical (unquantised) gravity produces entanglement. We show that their model does not produce entanglement. Even if the model produced entanglement, it would be mediated by the quantised matter interaction, and not gravity. scirate.com/arxiv/2511.0... 🧪⚛️

Well-informed and accurate takes on the current state of quantum computing by @dangaristo.bsky.social. Good listen if you're outside the field or just entering it and want to get an honest picture. Kudos for using the term "physics experiment" instead of "computer", and for coining "quantum FOMO".

Did you know that in 2015 quantum computers were supposed to go "faster than the universe"?

Hey @springernature.com, doesn't this look worth some press coverage from you as well?

"Our results show a classical supercomputer would require more power than the Sun—or, in fact, the combined power of all stars in the visible universe—to complete the same task in the same amount of time." But ChatGPT just gave me a long list of superheros that are more powerful than the sun!

Love the puzzles in the first section and their solutions in Appendix A. They address common misconceptions about quantum computing. arxiv.org/abs/2508.05720
