Fault-tolerant quantum simulation of generalized Hubbard models
Andreas Juul Bay-Smidt, Frederik Ravn Klausen, Christoph Sünderhauf +3
Quantum simulations of strongly interacting fermionic systems, such as those described by the Hubbard model, are promising candidates for useful early fault-tolerant quantum comput…
