 Quantum tunneling vs. thermal effects in
experiments on adiabatic quantum computing

Abstract. Traditional simulated annealing uses thermal fluctuations
for convergence in optimization problems. Quantum tunneling provides
a different mechanism for moving between states, with the potential
for reduced time scales and different outcomes. Thermal and quan-
tum annealing are compared in two concentration regimes of a model
disordered magnet, where the effects of quantum mechanics can be
tuned both by varying an applied magnetic field and by controlling the
strength of thermal coupling between the magnet and an external heat
bath. The results indicate that quantum annealing hastens convergence
to the final state, and that the quantum character of the final state can
be engineered thermodynamically.
