Encoding gauge theories in quantum systems — •Alessio Celi — Departament de Física, Universitat Autònoma de Barcelona, 08193 Bellaterra, Spain

In this talk, I will describe a quantum computation/simulation approach to gauge theories based on the encoding, the resolution of the local conservation law of the theory to reformulate it in terms of the physical states, the gauge invariant degrees of freedom. I will present successful applications of the encoding that ranges from the realization of topological gauge theories with ultracold atoms to the ab-initio continuum limit of 2D lattice gauge theories with tensor networks.
