Abstract

We study the performance of the Off-Diagonal Expansion quantum Monte Carlo algorithm on quantum spin glasses, specifically, 3-regular random antiferromagnets augmented with a transverse magnetic field. We demonstrate the advantages, sometimes by orders of magnitude, of the technique by comparing its runtimes against existing state-of-the-art schemes such as Path Integral quantum Monte Carlo and Stochastic Series Expansion.
