Multisite gates for state preparation in quantum simulation of the Bose-Hubbard model

Year: 2024

Type: article

Abstract: We construct a sequence of multisite gates which transform an easily constructed product state into an approximation to the superfluid ground state of the Bose-Hubbard model. The mapping is exact in the one-dimensional hard-core limit and for noninteracting particles in both one and two dimensions. The gate sequence has other applications, such as being used as part of a many-body interferometer which probes the existence of doublons.
