Bad Policy: Subjecting PhD students and postdocs to 4-year visa limits, subject to immigration officials' review. This bureaucratic overregulation will reduce US competitiveness and weaken US science. There needs to be more awareness and discussion of this terrible idea news.bgov.com/daily-labor-...

The QEC25 conference hosted by @yaleqi.bsky.social was really excellent, and videos of all talks are available. So much recent progress on quantum error correction! qec25.yalepages.org

"Every American taxpayer is a silent shareholder in that success. If we walk away now, we lose not just future breakthroughs but also what we have already earned." thehill.com/opinion/tech...

Rodney Baxter, Australia’s celebrated mathematical physicist, the Baxter of Yang-Baxter equations, passed away yesterday 🥲 en.wikipedia.org/wiki/Rodney_...

Both the House and Senate Committees on Appropriations have now passed funding for science agencies with moderate cuts and flat funding, respectively. Both bills are quite far from the president's budget request, which proposes massive cuts to science funding.

Andrew Houck, Director of the Co-Design Center for Quantum Advantage, makes an eloquent case for the value of the National Quantum Initiative Quantum Research Centers. Hey Congress, how's that reauthorization coming along?

On July 17-18 a small symposium "Dreams of Quantum" will be held in honor of David DiVincenzo's work and retirement at RWTH Aachen. The event can be attended via Zoom by all. Information about the program of speakers & the Zoom link can be found at www.quantuminfo.physik.rwth-aachen.de/cms/~bmmwed

Raymond Laflamme 1960-2025. A great scientist, renowned for his pioneering contributions to quantum error correction. A great leader, founding director of the Institute for Quantum Computing. A great colleague and teacher whose legacy continues to inspire us. uwaterloo.ca/institute-fo...

RIP Ray Laflamme, gone too soon. Ray was a stellar scientist, the founding director of ⁦‪the IQC‬⁩ and ⁦‪of CIFAR's‬⁩ Quantum Information program, but more importantly a warm & generous human who built community and helped many (particularly junior researchers). May his memory be a blessing.

Happy to see our book "Why Nobody Understands Quantum Physics" published in English www.panmacmillan.com/authors/fran.... Unlike other popular science books, we explain quantum and its applications in the way working physicists use and understand them, without shying away from the many-body problem.

My Canadian university, Queen's, is offering TWENTY 4-year funded PhDs (40k CAD/yr) for a student of ANY citizenship who has been accepted at a top 100 US university but have had offer rescinded OR are reconsidering offer due to US policy. Details found here👇 www.queensu.ca/grad-postdoc...

The US Administration has indefinitely blocked *all* student visa applicants from getting a visa interview. Worldwide, unconditional, no end date. All. International students are crucial to the US university system, American innovation, and future US prosperity.

This! I like to say, "Let p|A denote distribution p conditioned on event A. Imagine a world where the laws of probability are the same, except (p|A)|B need not equal (p|B)|A. Except you don't have to imagine, because it's literally our world! Now explore probabilistic algorithms in this world."

"Skinny" US budget out today w/ many cuts to specific programs + NSF now at 15% overhead. Silver lining: "[ NSF] Funding for Artificial Intelligence and quantum information sciences research is maintained at current levels."

I'm hiring a postdoc! If you'd like to work with me on quantum learning, error correction, quantum algorithms, and FTQC at Virginia Tech in the Washington, DC metro area, please apply here: careers.pageuppeople.com/968/cw/en-us...

This past week, I received a second stop work order on one of my grants. This now means that we can no longer spend on *two* of my major grants. Several of my group members will now graduate earlier than expected, I am looking into being a consultant for the summer, and students will do internships

New record for density of sphere packings in ℝ^n. Pretty big breakthrough! arxiv.org/abs/2504.05042

This is the abstract to their paper. Nice.

Blown away by the record-breaking 252 submissions to #QEC25! 🚀 Exceptional quality across theory and experiment—our community keeps raising the bar. Can’t wait to work with the PC to select an outstanding program. This conference is going to be amazing! 🎉

Great article. Tell me again why Ginsparg (and possibly Cohn as well) haven't been given all the prizes?

Only one week left to submit a contributed talk to QEC 25! qec25.yalepages.org August 11 - 15, 2025, hosted at Yale University. This promises to be the best QEC yet! Please repost!

Online Codes & Expansions (CodEx) Seminar Tues Mar 11 2025 Steve Flammia @sflammia.bsky.social "A Constructive Approach to Zauner’s Conjecture via the Stark Conjectures" using #NumberTheory to build #quantum SIC-POVMs. Based on bsky.app/profile/sfla... www.math.colostate.edu/~king/codex/. #🧮 ⚛️🧪

QIP 2026 is in Riga. Dates for QIP 2027 are preliminary

Everyone: AGI is imminent. ChatGPT:

I'll have to rework my grant to study marginalized probabilities and Bell's inequality.

Submissions for QEC 2025 are now open through March 28. This will easily be the most exciting conference on quantum error correction yet! Conference homepage: qec25.yalepages.org EasyChair submission page: easychair.org/my/conferenc...

Phasecraft internship applications are open! Anyone working on quantum info at an early stage (or adjacent fields!) who wants to experience working with a fantastic research team on cutting-edge quantum algorithms is welcome to get in touch :)

In German, the word "Schiedsrichtertrotzdank", means the simultaneous feeling of annoyance and gratitude you feel when a referee makes a valid point.

I'm thrilled to announce my latest work with Marcus Appleby and Gene Kopp, scirate.com/arxiv/2501.0.... In this paper, we attacked the notorious Zauner (SICPOVM) conjecture: "There exist d^2 equiangular lines in ℂ^d" It's deceptively simple, but has been open for 25+ years. 🧵 1/9

Today is the 40th anniversary of BB84.

A related, and much more difficult question: If there is (by definition?) one universe, shouldn't quantum cosmology study positive maps instead of completely positive maps?

To all the Gen Z that never had the pleasure of managing your own TeX distribution, today is your day!

We're hiring quantum theory faculty at Virginia Tech. This is an open-rank position in the CS or EE department at the new Center in Alexandria, VA, just outside of Washington, DC. This is the first of several new hires at the Center. Come join us (pls RT)! careers.pageuppeople.com/968/cw/en-us...
