论文摘要
网络超导量子计算机是量子科学的长期挑战。典型的方法是级联传感器：转换为发射器处的光频率和接收器处的微波频率。然而，小的微波光耦合和增加的噪声已被证明是巨大的障碍。取而代之的是，我们通过一种检测到的光子和传送方式通过先驱端到端的纠缠提出了光学网络。与级联的直接转导相反，我们的方案将低光 - 微波耦合效率吸收到先驱步骤中，从而破坏了利率的折衷权。此外，该技术统一并简化了量子网络中超导器件与其他物理方式之间的纠缠产生。
Networking superconducting quantum computers is a longstanding challenge in quantum science. The typical approach has been to cascade transducers: converting to optical frequencies at the transmitter and to microwave frequencies at the receiver. However, the small microwave-optical coupling and added noise have proven formidable obstacles. Instead, we propose optical networking via heralding end-to-end entanglement with one detected photon and teleportation. In contrast to cascaded direct transduction, our scheme absorbs the low optical-microwave coupling efficiency into the heralding step, thus breaking the rate-fidelity trade-off. Moreover, this technique unifies and simplifies entanglement generation between superconducting devices and other physical modalities in quantum networks.
