“…In this framework, high-energy physics represents an interesting testbed for quantum devices. On the one hand, quantum computation can be applied “downstream”, to optimize data analysis and event reconstruction from experiments [ 11 , 12 , 13 , 14 , 15 ]. On the other hand, the “upstream” investigation of gauge theories, especially in their lattice formulation [ 16 , 17 , 18 , 19 , 20 ], can benefit from the possibility of performing quantum simulations of regimes not achievable with perturbative techniques.…”
