That is exciting. I got to know Pieter-Jan Derks at the IBM QEC summer school in Tarrytown some years ago. That school produced a lot of great researchers in QEC. Good luck with the startup. Maybe we can run some of your tools on our QEC hardware.

Likely the most important thing I've ever written — if you're an academic and the AI mania unsettles you, here's my best shot at presenting some intellectual tools that might help you articulate why. arxiv.org/abs/2610.27251

#quantinuum QEC team absolutely killing it right now. Here's the latest results showing logical error rate down to 5x10^-6 with the colour code. On the Helios hardware. Get stuck in! #quantumcomputing #qec #quantum arxiv.org/abs/2610.24077

UK news really needs to get a grip. Don't press everything into some stupid, emotional reality game show format. The news isn't that Zelenskyy "felt" or "feels" betrayed. The main news should be that he and, more generally, Ukraine *was* betrayed by the US.

I would take more seriously the people promoting the idea of AI consciousness if they first materially grappled with the (much more obvious) consciousness of animals and how that affects our moral obligations to them.

I rather like this, it's quite clever people.cs.nott.ac.uk/pszgmh/flow-... . It was already decently documented that borrowing can be thought as a lens operation. What Wilshaw and Hutton add is that you have to consider how those lenses are composed.

Goddamn, this point by @anandwrites.bsky.social really needed saying.

Another long-held belief in QEC shattered. We live in a fun time. Congrats @vva.bsky.social! arxiv.org/abs/2610.06730

My team at @quantinuum.bsky.social is hiring a Principal Quantum Compiler Engineer! We're tackling some fascinating compiler problems on the path to fault-tolerant quantum computing. Come work with us or please share with someone who might be interested! jobs.eu.lever.co/quantinuum/6...

🚀 QuBriC officially starts today! QuBriC is building the foundations of scalable, fault-tolerant quantum computing while training the next generation of quantum researchers. 🎓 15 funded PhD positions! Interested? Explore the vacancies and join the future of quantum computing🔗 www.qubric.eu

Shame on @qipconference.bsky.social for using X/twitter. You give our community a bad name.

Hi #Edinburgh, your twin city #Kyiv is being bombed 24/7 and needs some attention. I know the bombing is not your fault, but silence can also be a crime. You were active when the full invasion started, but now interest seems to have waned?

I was in Toronto for IEEE #Quantum Week / IWQC / QRE. Here me giving a talk about #guppylang at etc Quantum Software 2.6 workshop and with my co-panelists, Rafael Haenel, Roger Luo, Brad Chase, Sebastian Feld, and Mathys Rennela. #guppy #quantumcomputing guppylang.org

I had the opportunity to attend the International Workshop on Quantum Compilation this past weekend at Xanadu headquarters in Toronto! #quantum #compiling #iwqc

I'll be speaking at this, at 13:00. Can't promise it will be good, but I'd be happy to see you!

Deeply saddened to learn that Rafael Sorkin is no more. One of the deepest and most original thinkers of quantum gravity and the pioneer of causal set theory, he was also among the nicest, gentlest physicists I have met.

For context, to ground the conversation and explain one of the issues. USD20M, which is a self-reported (likely low-balled) estimate of what OpenAI burned in *one week* in their scooping race, would fund 100 full-time postdoctoral positions for 2 years (including overhead). 100 postdocs. 2 years.

Indeed indeed. Et c'est pour ça que peut-être, on pourrait considérer laisser les gens habiter où ils veulent, non? Tous les gens. Dans n'importe quel pays. Plutôt que d'imposer des permis de résidence qui font qu'à tout moment une vie peut être bouleversée par une décision administrative.

Look, it's really simple: if its a work tool, your employer should pay for it, not you. Please don't contribute to normalizing “pay for your own work tools”.

Conferences suck. Little workshops are much better. I like this idea: www.argmin.net/p/microconfe...

Registration for IWQC 2026 has been extended to 31st August. If you want to hear about the state of the art of quantum compilers sign up while there is still space! It's happening at Xanadu HQ in Toronto 19 - 20 September. #iwqc #quantum #quantumcomputing quantum-compilers.github.io/iwqc2026/

Yet another job ad! We're looking for a software engineer to work on our open source Tierkreis workflow system (focussing on quantum-HPC hybrid integration). The job is based in Singapore. #quantumcomputing #jobad jobs.eu.lever.co/quantinuum/8...

Reading articles on the amounts HE has spent in APCs over the last 5-10 years, and slowly watching my blood pressure rise. Millions upon millions, on something WE CAN ABSOLUTELY DO OURSELVES FOR A FRACTION OF THE COST - what universities couldn't do with that kind of money now... 😠 And breathe...

Last day to submit your contribution to the quantum compilers workshop! We want a 3--5 pages abstract describing your best compiling ideas! #quantum #quantumcomputing #compilers #iwqc2026 quantum-compilers.github.io/iwqc2026/

At today's UKRI board meeting, the fate of UK particle physics and astronomy will likely be decided. Have we done enough to convince the powers-that-be to halt the proposed funding cuts? 🤞 Read Prof. Hiranya Peiris in Nature today eloquently explaining why these cuts are wrong.🧪🔭⚛️ 📖: rdcu.be/friwM

Here's Relational Intelligence. rel-int.ai Why? Current LLMs are unexplainable, no path to efficiency, no path to scalability... How? The same structure governs quantum mechanics and natural language, and cognition more generally. We use this to build AI whose reasoning you can trust. When? Now!

Do you like compiling quantum software? Maybe you should send something to the 8th International Workshop on Quantum Compilation? The deadline is the 10th of July! Tell your friends! (Just the cool ones.) quantum-compilers.github.io/iwqc2026/ #quantum #compilers #quantumcomputing #iwqc2026

My first Nature paper! I had very little to do with it :-) www.nature.com/articles/s41...

one anecdote: I was searching for a link to one of my old papers on Google, and the automated Gemini summary attributed all of my lab's work to my husband

this pattern is so silly. just put your damn artifacts online

Lightning talk submissions are open for the Quantum Software 2.6 workshop at IEEE Quantum Week in Toronto. Working on quantum software? We'd love to hear from you. Workshop: sites.google.com/view/quantum... Submit: forms.gle/fnSPSmERLSPq...

It would be very nice if quantum circuit benchmarking suites like MQTBench came with expected results for the circuits in 0 noise environments so that we can test against them. It's easy enough for things like W or GHZ generators but I have no clue what your Grover implementation was converging on

Do not let AI write for you.

International Workshop on Quantum Compilation is accepting submissions. The workshop is in Toronto 19--20 September. #quantum #compilers #quantumcomputing #cfp quantum-compilers.github.io/iwqc2026/

Friend of the shop @johncarlosbaez.bsky.social will be at Sloan's tomorrow!
