Fermion determinants on a quantum computer

Abstract

We present a quantum algorithm to compute the logarithm of the determinant of the fermion matrix, assuming access to a classical lattice gauge field configuration. The algorithm uses the quantum eigenvalue transform, and quantum mean estimation, giving a query complexity that scales like O(Vlog(V))O(V\log(V)) in the matrix dimension VV.
