A phonon blockade is achieved in a hybrid optomechanical system including an ensemble of two‐level quantum emitters. The introduction of the ensemble of quantum emitters sets up a mechanism of quantum destructive interference within the system, by which the phonon statistical characteristic exhibits strong antibunching under the condition of weak driving and weak coupling. By analyzing the analytic solution of the second‐order correlation function, the optimal parametric condition for ideal phonon blockade effect is obtained. The numerical simulation of the second‐order correlation function perfectly accord with the analytical solution. The validity of the effective Hamiltonian is proved by the numerical simulations with quantum master equation. The proposed scheme provides a possible way to realize the single‐phonon source experimentally.

Tavis-Cummings耦合光机械系统中的非常规声子封锁

在混合光机系统中实现声子阻挡，该系统包括两级量子发射器的集成。量子发射体集合的引入建立了系统内量子破坏性干涉的机制，通过该机制，声子的统计特性在弱驱动和弱耦合的情况下表现出较强的抗聚束性。通过分析二阶相关函数的解析解，得到理想声子阻挡效应的最佳参数条件。二阶相关函数的数值模拟与解析解完全吻合。通过量子主方程的数值模拟证明了有效哈密顿量的有效性。所提出的方案提供了一种通过实验实现单声子源的可能方法。
