Demonstramos uma abordagem híbrida quântica-clássica para explorar múltiplos problemas de conjunto máximo independente no estado de terra, em que o hardware quântico fornece as soluções iniciais e um algoritmo de pós-processamento totalmente clássico as expande, aumentando a diversidade de soluções de medições de hardware quântico por até várias ordens de magnitude. Dispositivos de otimização quântica, enquanto capazes de gerar soluções de alta qualidade, podem sofrer de limitações fundamentais de amostragem.

Abstract

We demonstrate a hybrid quantum-classical approach for exploring ground-state manifolds of maximum independent set problems, in which quantum hardware supplies the initial solutions and an entirely classical post-processing algorithm expands them, increasing the solution diversity of quantum hardware measurements by up to several orders of magnitude. Quantum optimization devices, while capable of generating high-quality solutions, can suffer from fundamental sampling limitations. This is particularly problematic for applications that strongly depend on a large variety of uncorrelated optimal s
