Multi-outlet single photon quantum router between optics and microwave based on a hybrid optomechanical system

Abstract

A Multi-outlet single photon quantum router between microwave and optical frequency domain is investigated in a system consisting of a superconducting microwave cavity and an optical nanomechanical cavity coupled to a commom nanomechanical resonator (NAMR). It is demonstration that the single-photon of optical frequency can be routed into three different output ports by adjusting microwave power. More importantly, the two output signals can be selected according to microwave power. Meanwhile, we also show that thermal noise will be insignificant for the optical performance of the single-photon router at temperature of the order of 20 mK. Our proposal may have paved a new avenue towards multi-channel router and quantum network.
