We present an approach to achieve bi-directional conversion between microwave and optical photons based on a hybrid waveguide-QED structure. The proposed converter combines both the merits of optomechanical system and superconducting circuits. Through analysis, we obtain two different impedance matching conditions to realize an ideal conversion efficiency close to unity. One of the matching conditions is owing to atom–phonon hybrid modes, which is different from the well known one due to dark modes. The underlying physical mechanism is discussed in detail. The performance of the setup under different matching conditions is also compared. The device studied here may be realizable in the future experiments, suitable for on-chip integrations, and may have potential applications in the future quantum networks.

我们提出了一种基于混合波导-QED 结构实现微波和光学光子之间双向转换的方法。所提出的转换器结合了光机械系统和超导电路的优点。通过分析，我们获得了两种不同的阻抗匹配条件，以实现接近于1的理想转换效率。匹配条件之一是由于原子 - 声子混合模式，这与众所周知的暗模式不同。详细讨论了潜在的物理机制。还比较了设置在不同匹配条件下的性能。这里研究的器件可能在未来的实验中可以实现，适用于片上集成，并可能在未来的量子网络中具有潜在的应用。
