I am a theoretical physicist working in quantum information science.

You can reach me on my email marc-olivier[dot]renou[at]inria[dot]fr

My research interests include the study of quantum correlations, quantum networks, distributed quantum computing, device-independent quantum information processing and non commutative polynomial optimization for quantum mechanics

Since February 2023, I have a Junior Professor Chair at INRIA Saclay affiliated with the Center for Theoretical Physics (CPHT) of Ecole Polytechnique. I will soon co-create a new INRIA project team in quantum information theory, at the interface between Physics and Computer Science.

Before this:

  • I was from 2020 to January 2023 a Marie Curie fellow (funded by Spain through the EU recovery fund) and an Early Postdoc.Mobility fellow (funded by Switzerland) at the Instituto de Ciencias Fotónicas (ICFO, Barcelona), in the Quantum Information Theory group led by Antonio Acín.
  • I did in the summer 2022 a long research stay at ETH Zürich in the Quantum Information Theory group led by Renato Renner.
  • I did my PhD in 2015-2019 under the supervision of Nicolas Gisin at the University of Geneva.

News

I had several great news recently:
Two accepted papers at STOC 2024, the most prestigious conference in theoretical computer science:
– No distributed quantum advantage for approximate graph coloring, a colaboration wih the teams of Jukka Suomela (Aalto University) and François le Gall (Nagoya University) focussing on the LOCAL model of distributed computing. We prove bounds on the capabilities of quantum information theory for a large family of synchronous distributed computing problems.
– Nonlocality under Computational Assumptions. In this paper, we introduce computational assumptions to reformulate foundational quantum information questions considered by quantum physicists, such as the relations between entanglement and nonlocality. This initial idea was very nicely complemented by my co-authors Khashayar Barooti and Grzegorz Głuch, we also show that the answers to these foundational quantum information questions would have direct consequences for quantum complexity and cryptography
Our QuantERA project COMPUTE was accepted! QuantERA is highly selective, COMPUTE is a joint project at the interface between pure maths (operator theory), noncommutative polynomial optiization and quantum information theory. In particular, we will mathematically understand algorithmic methods to tackle quantum networks problems, and numrically develop them. I’ll coordinate this project, which involves researchers in quantum information theory (Mariami Gachechiladze, Antonio Acín, David Gross, myself), pure math (Igor Klep, Aljaž Zalar) and optimization (Victor Magron).
PhiQus, our proposed joint Inria Saclay – CPHT – LIX team with Filippo Vicentini and Titouan Carette,should be created soon! We recently discussed the potential creation of PhiQus with Inria Saclay scientific commission, Ecole Polytechnique and even CNRS, everyone is enthusiastic!
