摘要

Abstract

Quantum receivers aim to effectively navigate the vast quantum-state space to endow quantum information processing capabilities unmatched by classical receivers. To date

only a handful of quantum receivers have been constructed to tackle the problem of discriminating coherent states. Quantum receivers designed by analytical approaches

however

are incapable of effectively adapting to diverse environmental conditions

resulting in their quickly diminishing performance as the operational complexities increase. Here

we present a general architecture

dubbed the quantum receiver enhanced by adaptive learning

to adapt quantum receiver structures to diverse operational conditions. The adaptively learned quantum receiver is experimentally implemented in a hardware platform with record-high efficiency. Combining the architecture and the experimental advances

the error rate is reduced up to 40% over the standard quantum limit in two coherent-state encoding schemes.
