Congratulations to @qubobs.bsky.social for their #QIP2026 poster award! @irif-paris.bsky.social @cnrs.fr @upcite.bsky.social

With a best poster award!

Some photos from the poster session. Thanks to everyone who stopped by!

Peter Shor: we haven't found many new quantum algorithms, in part, because we need larger quantum devices for testing our heuristics. He gives several examples of algorithms that were discovered computationally, including turbo codes, @fermilab.bsky.social quantum symposium by the SQMS center.

Brève de Science : protéger les données sensibles L’adage “si c’est gratuit, c’est vous le produit“ n’a jamais été aussi vrai qu’aujourd’hui sur Internet.

🔐 Applications de rencontre, rendez-vous médical en ligne… La gratuité repose souvent sur la collecte et l'exploitation de nos données personnelles. Comment garantir leur sécurité ?
C’est l’enjeu des travaux de Geoffroy Couteau, cryptographe CNRS au sein de @irif-paris.bsky.social.

Here is the answer of ChatGPT: Only if your research frequently involves multimodal, long-context, or data-extraction tasks that ChatGPT + Claude do not handle well.
For deep reasoning, accuracy, and scholarly reliability, Gemini is currently weaker and provides limited incremental value.

I recommend the savetrees package!

Once again, and especially for this International Year of Quantum Science and Technology #IQY2025, I'm very proud of @irif-paris.bsky.social and #MPQ lab for participating in the science festival at @upcite.bsky.social on October 8th and 10th.

Does it start with a Q?

AI, my students and me: 'Last semester marks the nadir of my experience in academia' 'Letters from America' (1/6). The writer and journalist Thomas Chatterton Williams has been startled by the omnipresence of artificial intelligence at university, which he believes threatens the very ...

I’m an award-winning mathematician. Trump just cut my funding. The “Mozart of Math” tried to stay out of politics. Then it came for his research.

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

“Le futur Palais de la découverte est moderne et prêt à être installé”, Étienne Ghys. Le 8 août 2025, La Recherche a interrogé le mathématicien Étienne Ghys, secrétaire perpétuel de l’Académie des sciences, sur l’avenir incertain et le programme scientifique du Palais de la découverte à Paris.

New Method Is the Fastest Way To Find the Best Routes | Quanta Magazine A canonical problem in computer science is to find the shortest route to every point in a network. A new approach beats the classic algorithm taught in textbooks.

This is very impressive. Breaking the sorting barrier for directed single source shortest paths

Indeed, I was fortunate to be hosted by @ccanonne.github.io in the amazing SACT group @sydneycompsci.bsky.social for a little over a week. Many thanks to the whole group for the warm welcome and for the exciting projects I’m now bringing back to France at @irif-paris.bsky.social!

Springer publishes a P ≠ NP "proof" and Eric Allender has words to say.

And they boycott ICALP!

Do you have a link to a(ny) paper? Similar techniques exist in quantum query complexity. I was wondering if they are any similarities.

Wonderful! Is it possible to attend online or to get the recording talks later on?
