我们报道了在辐射压力下机械谐振器运动介导的两种微波模式之间有效和低噪声的频率转换的观察。我们实现了超过10（12）个光子/秒的相干转换，效率为95%，带宽为14 kHz。光子少于10（-1）的。(1)。当外加噪声为Hz（-1）时，该光机械变频器适用于量子态转导。我们展示了将该转换器作为可调谐分束器操作的能力，直接应用于光子路由和通过复杂量子网络的通信。
We report the observation of efficient and low-noise frequency conversion between two microwave modes, mediated by the motion of a mechanical resonator subjected to radiation pressure. We achieve coherent conversion of more than 10(12) photons/s with a 95% efficiency and a 14 kHz bandwidth. With less than 10(-1) photons . s(-1) . Hz(-1) of added noise, this optomechanical frequency converter is suitable for quantum state transduction. We show the ability to operate this converter as a tunable beam splitter, with direct applications for photon routing and communication through complex quantum networks.
