After a master in theoretical physics at the Ecole Normale Supérieure of Lyon and an engineering degree from Ecole Centrale Lyon (France), I have earned a PhD from Ecole Polytechnique (Palaiseau, France). My doctoral research, supervised by Michel Ferrero (Centre de Physique Théorique - CPHT, Collège de France) and Thomas Ayral (Atos - Eviden Quantum Lab) aimed at understanding how one could take advantage of quantum computation in the noisy era to describe strong inter-electronic correlations within the Dynamical Mean-Field Theory framework. My main result is an advanced variational scheme to prepare the ground states of fermionic systems in spite of high noise levels. I also co-authored a review article regarding quantum computing applied to the many-body problem.
