- Abstract: A nonlocal circulator protocol is proposed in 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 optical mode and two mechanical modes are 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.
