Ph.D. in Quantum Info at ICFO. Now at UNIGE, previously at ICMAT and Universidad Complutense de Madrid. La Caixa & SNSF fellow. Quantum ⚛️ & AI . Erdös number: 4.
Yay! Forms are so much fun 🎉🎊 If you're a quantum researcher, we would love it if you could fill the form (<10 minutes) and share it with your network. Thanks!
My good friend and famed lover of questionnaires @eliesgf.bsky.social has a simple question for the quantum info community: what do you think when you hear the terms "strong" and "weak simulation? He (and by extension, me) would love it if you filled in this Google Form! forms.gle/wfFcwBPdaafv...

After extensive experiments with AI agents, the [72,36,16] extremal code remains elusive—and possibly more intractable than we expected. This isn’t your average Erdős puzzle; it’s full-stack math + compute. We’re opening the search to the community: take a shot. valbert4.github.io/selfdual_site/

PhD opportunity in QIT in Grenoble. I am advertising a project through the QuanG2 call, at the interface of nonlocality, self-testing, computationally bounded devices, complexity, and crypto. My project is among the topics offered: phdquantumgrenoble.univ-grenoble-alpes.fr/phd-applicat...

wow — the preprint host, arxiv, is banning authors for a year if they submit papers with hallucinated citations 🤖
I find this unsettling: A new study in #Lancet shows that the number of faux citations in scientific articles is on the rise, and #AI is likely to blame. @aniloza.bsky.social reports. www.statnews.com/2026/05/07/l...
This week I am visiting @quaintum.bsky.social at @univ-amu.fr. This is definitely the most beautiful campus I've been to so far. Looking forward to the exciting discussions!
📢 New paper out! We have found the smallest (and arguably simplest) realization of nonlocality in quantum networks. In fact, this result refutes an 8-year-old conjecture! www.scirate.com/arxiv/2605.0... 1/n @snsf.ch @sorbonne-universite.fr @uniulm.bsky.social @jagiellonskiuni.bsky.social
The minimal example of quantum network Bell nonlocality
In recent years, the study of Bell nonlocality has been generalized to quantum networks, where multiple independent sources distribute physical systems to distant parties who perform local measurement...

Today, as part of our Strategy on Quantum Technoolgies, @csic.es announced the creation of a new research institute in Madrid, the Quantum Advanced Research Center or QuARC @quarc-csic.bsky.social This new institute launches now with 24 PIs and a total of 100 researchers 1/ quarc.csic.es

This was a super interesting read for me as a quantum physicist. I learnt that zero-knowledge provers can be hacked, and that cryptographers' and security analysts' way of understanding quantum mechanics is completely different to ours. What an interesting time to live in!
Two weeks ago, Google published a paper proving in zero-knowledge that they had an efficient implementation of Shor's algorithm. Today, Trail of Bits can prove that we have an even better implementation which beats Google's on all metrics! 🫢 blog.trailofbits.com/2026/04/17/w...
A little task to get your brain going today: Prove the statement in the picture!
We are living in exciting times. Starting today, the zoo will be completely redone by AI! errorcorrectionzoo.org/__41ai
About
The Error Correction Zoo collects and organizes error-correcting codes.

Copilot will use your code for model training starting next month unless you opt out 👇 If you’re a student on the free plan, consider whether you want to disable this before April 24th
Celebrate with us Quantum's approaching 10 year anniversary in 2026 with the publication of the 2026th paper! Do you know which paper that is? quantum-journal.org/2026-quantum...

Today I spoke about quantum nonlocality in networks at the "Nonlocality: Driver for Quantum Advantage?" workshop at the @lorentzcenter.bsky.social. After the first day of the workshop, I'm eager to see what the rest of the week brings. @snsf.ch
Some quantum info researchers are reluctant to learn about non-CPTP maps, but are ultimately left with no Chois.

This is the last week to apply to the Spring School in near-term quantum computing that we are organizing at @ccbpp.bsky.social. Don't miss it!
The @ccbpp.bsky.social Spring School on near-term quantum computing is back! If you are a young (PhD/MSc) researcher in quantum science and want to get exposed to the recent developments on quantum computing, do not hesitate coming to Benasque on March 15 - 21 next year! www.benasque.org/2026ntqc/
Happy 2026, and hearty Congratulations to Antoine Browaeys, Misha Lukin, and Mark Saffman on the 9th biennial John Stewart Bell Prize for their ground-breaking work developing quantum computational technologies relying on tweezer arrays of Rydberg atoms! cqiqc.physics.utoronto.ca/bell-prize/b...
I was not expecting this for Christmas, at all. I am truly grateful for having my research being recognized this way. Thanks to @ioppublishing.bsky.social @iopp-quantum.bsky.social for this prize! iopscience.iop.org/journal/2058...

OpenAI leadership are promoting a paper in Physics Letters B where GPT-5 proposed the main idea — possibly the first peer-reviewed paper where an LLM generated the core contribution. One small problem: GPT-5's idea tests the wrong thing. My technical comment: scirate.com/arxiv/2512.0... 1/
