#QReads 2/? Coms Complexity by Kushilevitz and Nisan—a key reference in the 2001 Q Coms Complexity survey. A topic I am exploring. This is a pen-and-notebook kind of book, so it rarely leaves my office. But sundown over Edinburgh makes an ideal backdrop for coffee and complexity problems.

Interested in contributing to quantum open-source projects while getting paid over the summer? toqito, a quantum information toolkit, is participating in Google Summer of Code 2025 through @numfocus.bsky.social. You can find a list of potential project ideas in the project wiki.

#QReads 1/? Starting with Categories in Context by E. Riehl—the all-knowing grad math student’s dream intro to category theory—against Lisbon. Best category intro for a physicist? Probs not Has my reading group made it halfway (still plowing)? Yes! Did I learn tons deciphering the e.g.? Absolutely

#QReads 0/? I have recently found myself with interesting quantum books and “big” papers while visiting cool places. Although rare, it’s happened often enough for me to be able to start a miniseries. If the stars continue to align, I’ll continue sharing them here.

A new theory, that explains quantum light and matter interactions has enabled researchers to define the shape of a photon! Very cool! "almost as a bi-product of the model, we were able to produce this image of a photon"~ Dr Benjamin Yuen, Uni of Birmingham www.birmingham.ac.uk/news/2024/ne...

Error-free computation wasn’t always a given in computing. In the ’40s and ’50s, chips relied on unreliable components. Today, we just remind people that cosmic rays might cause errors. But hey, fully quantum error corrected devices are too far-fetched… youtu.be/IkRXpFIRUl4?...

I am happy to announce that the Kakeya set conjecture, one of the most sought after open problems in geometric measure theory, has now been proven (in three dimensions) by Hong Wang and Joshua Zahl! arxiv.org/abs/2502.17655 I discuss some ideas of the proof at terrytao.wordpress.com/2025/02/25/t...

"Today’s Noisy Intermediate-Scale Quantum (NISQ) computers have scientific value, but quantum machines with broad practical value must be protected against noise using quantum error correction and fault-tolerant protocols." -- @preskill.bsky.social Megaquop era is upon us! arxiv.org/abs/2502.17368

Never been more curious to understand topological qubits. All in for the Microsoft drama 💅 @preskill.bsky.social ‘s 2004 notes

One day there will be a show about maths that—instead of showing a spotless white-walled room covered in equations or glass panels with equations readable from the wrong side—focuses on things mathematicians care about, viz, coffee, wearing shorts all year round, and a free supply of Hagoromo chalk.

According to our count, there are now 100 quantum PhD students on Bluesky! Also 25 people so far came over from X using our starter pack. go.bsky.app/AUTn1di

Computer scientists Harry Buhrman (left) and Michal Koucký (right) helped prove that, if you tweak bits in just the right way, you can get extra computational oomph out of a full memory. https://buff.ly/4i6G7Tz

I do wonder if this is going through the minds at Microsoft at the moment (hopefully they did find something 🤞). Quote is from the Skepticism of QC chapter of QC since Democritus. A book that I have taken shamefully long to discover and that should be the follow up to Nielsen and Chuang imo 😂

Hello 👋 I am trying to put together a list of all journals and conferences that people in quantum publish in. If you have some favourites please let me know! - It would also be useful to hear some personal opinions and stories about these journals or conferences - who should we avoid and why?
