An efficient optical interconnect for superconducting quantum computers

该项目旨在开发将超导量子计算机连接到未来量子互联网的技术：光学互连。超导量子比特是一种领先的量子计算系统，但它们的实际应用受到其微波工作频率的限制，因为全球量子网络将在光频率下工作。该项目旨在通过将携带超导量子信息的微波光子转换为光学光子来解决这一问题。为了实现高效率，该项目将研究磁有序的稀土晶体，这种晶体具有独特的强光学和微波耦合能力，以建立一个可以大大提高量子计算机能力的转换器。

This project aims to develop the technology to connect superconducting quantum computers to the future quantum internet: an optical interconnect. Superconducting qubits are a leading quantum computing system, but their practical use is limited by their microwave operation frequency, as global quantum networks will operate at optical frequencies. This project aims to solve this problem by converting the microwave photons that carry superconducting quantum information to optical photons. To achieve high efficiency the project will investigate magnetically ordered rare-earth crystals, which uniquely possess the strong optical and microwave coupling required, to build a converter that could greatly enhance the capabilities of quantum computers.
