Badanie jakości rozwiązań wyżarzacza kwantowego D-Wave w reżimie diabatycznym
Although recent studies [1,2] have demonstrated high coherence of D-Wave hardware on short time scales, previous limitations of the API have prevented end users from independently verifying these results. Currently, access to this time scale has been made available, but only for a limited set of models, which hinders a full assessment of the hardware’s performance. As part of the project, we plan to develop a procedure to evaluate the behavior of the D-Wave annealer in the diabatic regime despite these limitations. In light of the consistent superiority of classical algorithms [3], particular emphasis will be placed on analyzing the impact of errors and interactions with the environment on the quality of the solutions obtained.
The proposed project is an extension of research conducted during my stay at Los Alamos National Laboratory. The preliminary results obtained pertain to the theoretical case of a closed system. As part of further work, we plan to extend the analysis to a more realistic case of an open system, in which interactions with the environment are present.
The planned tangible outcome of the project will be the preparation of a scientific publication.
