Nonlocal nonreciprocal optomechanical circulator

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