About the research centre or Inria department

The Inria Saclay-Île-de-France Research Centre was established in 2008. It has developed as part of

the Saclay site in partnership with Paris-Saclay University and with the Institut Polytechnique de

Paris .

The centre has 39 project teams , 27 of which operate jointly with Paris-Saclay University and the

Institut Polytechnique de Paris; Its activities occupy over 600 people, scientists and research and

innovation support staff, including 44 different nationalities.


The research project will explore quantum protocols based on the concept of quantum nonlocality and quantum networks (see arXiv:2104.10700). A non-exhaustive list of potential projects is:

  • Methods for characterizing quantum correlations beyond the Bell scenario:
    • mathematical foundation of these methods (C* algebras, noncommutative polynomial optimization): see e.g. arXiv:2210.09065, arXiv:2212.11299, arXiv:2301.12513
    • improve/find new algorithms for characterizing these correlations
    • numerical developpement of these algorithms, see e.g. arXiv:2211.04483
  • Understanding the foundational implications of quantum correlations in networks, see e.g. arXiv:2101.10873 and arXiv:2105.09381
  • Develop the applications of network nonlocality to certification protocols, such as
    • randomness generation: arXiv:2209.09921 
    • self testing of measurements and states: arXiv:1807.04956, arXiv:2201.05032
  • Adapt existing protocols for their experimental implementation
  • Develop practical benchmarks of the concept of ‘Genuine Multipartite Nonlocality’ introduced in arXiv:2105.09381
  • Develop SDP relaxations for condensed matter problems, see e.g. arXiv:2212.03014, arXiv:2310.05844, arXiv:2311.18707, arXiv:2311.18706 
  • Explore the limits of quantum distributed computing, see e.g. arXiv:1810.10838, arXiv:0903.113

Any other suggested research project in quantum information theory can be discussed (both from the physics, the computer science or the mathematical viewpoint).

Main activities

The position will be funded through a QuantERA project involving a large european consortium: see the project website

It will be achieved by collaborating with Marc-Olivier Renou, other members of the group (Xiangling Xu, Lucas Tendick, Isadora Veeren, and also Titouan Carette and Filippo Vicentini), as well as the consortium members:

  • Mariami Gachechiladze (TU Darmstadt, Germany) and David Gross (Cologne)
  • Victor Magron (LAAS-CNRS, Toulouse, France)
  • Igor Klep (University of Ljubljana, Slovenia)
  • Antonio Acín (ICFO Barcelona, Spain)

Long stays in the groups of the consortium members will be encouraged.


The applicant should hold a PhD degree in computer science, physics, mathematics, or a related field and have an excellent track record of publications in quantum information theory. Familiarity with Bell nonlocality, operator algebras, SDP relaxations of polynomial optimization problems, quantum correlation protocols, experimental physics and / or synchronous distributed computing is a plus.
