I am Lecturer in the Informatics and Interactions department of Aix Marseille University and a researcher in the CaNa team of the LIS laboratory. I got my HDR in Computer Science at AMU and earlier on I did my Ph.D in Theoretical Quantum Physics at the Université Pierre et Marie Curie (Sorbonne).


My research activities take place in discrete mathematics and theoretical computer science and deals with quantum cellular automata, simulations, models and algorithms.

I am member of the Scientific Council (CSI) of the INS2I.

Geodesic Quantum Walk


Geodesic Quantum Walks represent a new and very general class of discrete time discrete space systems which is capable to flatten any curved triangulation onto a flat circuit with inhomogeneous gates. Relevant for both modeling and simulating quantum transport on curved discret structures as fullerene molecules, this could introduce new quantum curved space optimisation methods.

A discrete relativistic spacetime formalism for 1 + 1-QED with continuum limits


We show that, in the continuous-time discrete-space limit, the introduced QCA converges to the Kogut-Susskind staggered version of 1 + 1 QED. We also show that, in the continuous spacetime limit and in the free one particle sector, it converges to the Dirac equation—a strong indication that the model remains accurate in the relativistic regime.

A nonlinear charged quantum relativistic fluids is simulated via a new hybrid (quantum-classical) algorithm on NISQ devices. This work demonstrates that nonlinear fluid dynamics can be simulated on NISQs, and opens the door to simulating other, quantum and non-quantum fluids, including plasmas, with more general quantum walks and quantum automata.

Gauge-invariance in cellular automata


Gauge-invariance is a fundamental concept in Physics known to provide mathematical justification for the fundamental forces. In this paper, we provide discrete counterparts to the main gauge theoretical concepts directly in terms of cellular automata.

Spatial search with multiple marked vertices is optimal for almost all queries and its quantum advantage is not always guaranteed


We contribute to fulfil the long-lasting gap in the understanding of the spatial search with multiple marked vertices. Here (i) we provide strong numerical evidence that spatial configurations are almost all optimal; and (ii) we analytically prove that the quantum advantage with respect to the classical counterpart is not always granted.

A relativistic discrete spacetime formulation of 3+1 QED


This work provides a relativistic, digital quantum simulation scheme for 3+1 quantum electrodynamics (QED), based on a discrete spacetime formulation of theory. It takes the form of a quantum circuit, infinitely repeating across space and time. Strict causality is ensured as circuit wires coincide with the lightlike worldlines of QED; simulation time under decoherence is optimized.
