SAFE ma-QAOA achieves 64.3% fewer active parameters and 94.5% lower estimated QPU workload via surrogate pre-training and parameter distillation on Sherrington-Kirkpatrick, 2D spin glass, and Max-Cut instances.
SGIR-QAOA uses spectral gap information to create non-linear parameter schedules that outperform linear ramps on Grover's problem and MIS, achieving target probabilities at lower depths even under mild noise.
