Abstract
An experimentally accessible tunable single-photon multi-channel quantum router is investigated in a system consisting of an optomechanics cavity coulomb coupling to a nano-mechanical resonator. The router can extract a single-photon from the coherent input signal directly modulate into three different output channels, and the output probability is all close to 1. More important, the two output signal frequencies can be selected by adjusting Coulomb coupling strength. We also demonstrate the vacuum and 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.
