Nonreciprocal Phonon Blockade in a Spinning Acoustic Ring Cavity Coupled to a Two-Level System

Quantum nonreciprocal devices have received extensive attention in recent years because they can be used to realize unidirectional quantum routing and noise isolation. In this work, we show that the shift of resonance frequencies propagating phonons induced by spin-orbit interactions (SOI) a rotating acoustic ring cavity phonon blockade. When driving from different directions, single-, two-phonon blockade phonon-induced tunneling take place varying parameters system an appropriate value. To blockade, sublevels lower orbit branch ground state silicon-vacancy (SiV) color centers diamond membrane are employed induce self-interactions cavity. This work provides way achieve devices, such as directional switches isolation, which may help information network processing.
