论文摘要
量子网络可能会对我们将来的计算和交流方式产生深远的影响。为了将超导量子处理器连接到公里尺度的距离上，我们需要具有高忠诚度之间的微波炉和光学域之间的纠缠剂。我们提出了一个集成的电渗透传感器，该换能器将低损失的尼奥贝特光子锂与蓝宝石底物上的超导微波谐振器相结合。我们的Triply谐振设备在稀释冰箱中运行，并将微波光子转换为光子光子，其芯片效率为$ 6.6 \ times 10^{ - 6} $，转换带宽为20 MHz。我们讨论了该设备中的设计权衡，包括管理声学损失的策略，并概述了提高未来转换效率的方法。
Quantum networks are likely to have a profound impact on the way we compute and communicate in the future. In order to wire together superconducting quantum processors over kilometer-scale distances, we need transducers that can generate entanglement between the microwave and optical domains with high fidelity. We present an integrated electro-optic transducer that combines low-loss lithium niobate photonics with superconducting microwave resonators on a sapphire substrate. Our triply-resonant device operates in a dilution refrigerator and converts microwave photons to optical photons with an on-chip efficiency of $6.6\times 10^{-6}$ and a conversion bandwidth of 20 MHz. We discuss design trade-offs in this device, including strategies to manage acoustic loss, and outline ways to increase the conversion efficiency in the future.
