DF-SQD: Deterministic Fields for Sampling-Based Quantum Diagonalization

DF-SQD is introduced, a hybrid algorithm that derives deterministic auxiliary-field circuits from selected double-factorization leaves of the two-electron tensor and is able to discover better results with shallower circuits, is sample efficient, uses configuration recovery and has empirical convergence observation.
