Efficient quantum algorithm for Heisenberg spin systems
An efficient quantum adiabatic algorithm is obtained for the ground energy of any model in this family of Heisenberg-type quantum spin systems, based on a new inequality that relates the spectral gap of a positive semidefinite operator to its Lee-Yang radius.
