Quantum Optimization of Fully-Connected Spin Glasses
Davide Venturelli, et al. 
The Sherrington-Kirkpatrick model with random ±1 couplings is programmed on the D-Wave Two annealer featuring 509 qubits interacting on a Chimera-type graph. The performance of the optimizer compares and correlates to simulated annealing. When considering the effect of the static noise, which degrades the performance of the annealer, one can estimate an improvement on the comparative scaling of the two methods in favor of the D-Wave machine. The optimal choice of parameters of the embedding on the Chimera graph is shown to be associated with the emergence of the spin-glass critical temperature of the embedded problem.
