Quantum simulations of lattice gauge theories

In PASQuanS, alongside the actual development of the quantum simulators, we develop and exploit novel classical numerical methods to benchmark the future quantum simulations and establish the quantum advantage threshold, that is, the border of the physically relevant phenomena that can be classically simulated. One of the most challenging direction we explored is the classical numerical study of lattice gauge theories in regimes where Monte Carlo simulations are not efficient. We presented state of the art simulations of two dimensional lattice gauge theories at finite densities performed via tensor network methods (see http://arxiv.org/abs/1911.09693).
