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...
A scheme to prepare a 3D entangled state between a pair of Rydberg atoms via dissipative dynamics and electromagnetic induced transparency associated with the single‐atom dark state is proposed. The prepared entangled state is the dark state of the whole system. The scheme is also feasible regardless of initial purity or mixed state. Since the proposed scheme is based on the Rydberg block regime,...
