Degeneracy Counting Quantum Algorithm using Decoherence

The canonical thermal pure quantum (CTPQ) state-based degeneracy counting (CTPQsd#) algorithm is developed that determines the number of global optima of a classical optimization problem P by measuring only a small probe S, without finding individual minima.

Comparison of D-Wave Quantum Annealing and Gibbs Monte Carlo for Sampling from a Probability Distribution of a Restricted Boltzmann Machine

A local-valley (LV)-centered approach to assessing the quality of sampling from Restricted Boltzmann Machines (RBMs) was applied to the latest generation of the D-Wave quantum annealer, revealing some potential for improvement, e.g., using a combined classical–quantum approach.
