摘　　要：A nonlocal circulator protocol is proposed in a hybrid optomechanical system.By analogy with quantum communication,using the input-output relationship,we establish the quantum channel between two optical modes with long-range.The three-body nonlocal interaction between the cavity and the two oscillators is obtained by eliminating the optomechanical cavity mode and verifying the Bell-CHSH inequality of continuous variables.By introducing the phase accumulation between cyclic interactions,the unidirectional transmission of quantum state between the optical mode and two mechanical modes is achieved.The results show that nonreciprocal transmissions are achieved as long as the accumulated phase reaches a certain value.In addition,the effective interaction parameters in our system are amplified,which reduces the difficulty of the implementation of our protocol.Our research can provide potential applications for nonlocal manipulation and transmission control of quantum platforms.
