Professor at University of Paris-Saclay, leader of the “Quantum Computation Structures” group. During his PhD at U. of Cambridge, Pablo designed the first blind quantum computing protocol. As a lecturer in Grenoble, he pioneered the study of quantum programming languages and established fundamental results on quantum cellular automata (structure, universality, quantum simulation). As a prof. in Marseille, he generalized cellular automata theory to arbitrary graphs. Lately he explores the quantum regime of these causal graph dynamics, as a possible mathematical setting for quantum gravity.
