论文摘要
可逆地将光学和微波量子信号转换为彼此的有效转导设备对于整合不同的技术至关重要。固体中的稀土离子，尤其是具有光学和微波可寻址过渡的Erbium离子是设计换能器的有希望的候选者。我们在$ \ mathrm {^{167} er}中基于暗状态协议提出了一个微波至光学量子换能器方案，该方案在零外部磁场上掺入Yttrium Orthosilicate（YSO）中。零场的操作对可以在磁场中造成额外损失的超导谐振器有益。通过计算换能器的忠诚度和效率，考虑到最重要的缺陷，我们表明，具有高忠诚度是可能的。我们还研究了可用于传感器协议的$ \ mathrm {^{167} er} $的微波过渡。
Efficient transduction devices that reversibly convert optical and microwave quantum signals into each other are essential for integrating different technologies. Rare-earth ions in solids, and in particular Erbium ions, with both optical and microwave addressable transitions are promising candidates for designing transducers. We propose a microwave-to-optical quantum transducer scheme based on the dark state protocol in $\mathrm{^{167}Er}$ doped into yttrium orthosilicate (YSO) at zero external magnetic fields. Zero-field operation is beneficial for superconducting resonators that can incur extra losses in magnetic fields. By calculating the fidelity and efficiency of the transducer, considering the most important imperfections, we show that an efficient conversion is possible with a high fidelity. We also investigate the microwave transitions of $\mathrm{^{167}Er}$:YSO that can be used for the transducer protocol.
