摘要: We extend the classical forbidden-interval theorems for a stochastic-resonance noise benefit in nonlinear system to quantum-optical communication model and continuous-variable quantum key distribution model. Each theorem gives necessary sufficient condition that determines whether stochastic resonance occurs of messages. The apply any source has finite variance or comes from family infinite-variance alpha-stable probability densities. Simulations show benefits basic
