Abstract

Diabatic quantum annealing aims to mitigate the challenges posed by small energy gaps and decoherence in quantum optimization by exploiting nonadiabatic transitions. In this paper, we compare the performance of two diabatic protocols in a realistic, dissipative setting using the maximum weighted independent set problem as a test case, showing that the potential advantages of diabatic protocols are strongly reduced in the presence of dissipation. Our results highlight the importance of evaluating quantum annealing strategies under practical conditions.
