Adaptive, problem-tailored variational quantum eigensolver mitigates rough parameter landscapes and barren plateaus
Abstract Variational quantum eigensolvers (VQEs) represent a powerful class of hybrid quantum-classical algorithms for computing molecular energies. Various numerical issues exist for these methods, however, including barren plateaus and large numbers of local minima. In this work, we consider the A...
