Bounding the asymptotic quantum value of all multipartite compiled non-local games Non-local games are a powerful tool to distinguish between correlations possible in classical and quantum worlds. Kalai et al. (STOC'23) proposed a compiler that converts multipartite non-local games ...

We’ve just posted a new paper on arXiv!

Tackling this problem pushed us deep into the world of C*-algebras, leading us to prove some new results along the way and learn a lot. Kudos to Matilde, Dominik and Siniša, I’m really happy with how it all came together!

Translating Bell Non-Locality to Prepare-and-Measure Scenarios under Dimensional Constraints Understanding the connections between different quantum information protocols has been proven fruitful for both theoretical insights and experimental applications. In this work, we explore the relatio...

New paper today on arXiv with LIP6 friends on translating parallel (Bell nonlocal) to sequential (prepare-and-measure) protocols preserving the optimal quantum strategies.

This week I enjoyed the mini workshop organised by the very active group of M. O. Renou. Great scientific and non-scientific discussions and craaazy pretty French Alpes.

Worth a read written by a Palestinian struggling to survive amongst the settler's in Hebron.. if you haven't already you should watch the #LouisTheroux documentary The Settlers it's insightful and terrifying..

A month ago I started working in Grenoble as a CNRS researcher. Quite impressive city, have to say 🙃

Hola Bluesky! We have a new preprint, showing how to self-test in the Bell scenario all pure entangled qubit states involving an arbitrary number of parties and having arbitrarily 'complex' structure. It is the work we started long ago with Miqueleta, Andrea, Remik and Toni. arxiv.org/abs/2412.13266
