Approaching the Ground State of a Quantum Spin Glass using a Zero-Temperature Quantum Monte Carlo
Abstract
Here we discuss the annealing behavior of an infinite-range J Ising spin glass in presence of a transverse field using a zero-temperature quantum Monte Carlo. Within the simulation scheme, we demonstrate that quantum annealing not only helps finding the ground state of a classical spin glass, but can also help simulating the ground state of a quantum spin glass, in particularly, when the transverse field is low, much more efficiently.
