We introduce an adaptable and modular hybrid architecture designed for fault-tolerant quantum computing. It combines quantum emitters and linear-optical entangling gates to leverage the strength of both matter-based and photonic-based approaches. A key feature of the architecture is its practicality, grounded in the utilisation of experimentally proven optical components. Our framework enables the execution of any quantum error correcting code, but in particular maintains scalability for low-density parity check codes by exploiting built-in non-local connectivity through distant optical links. To gauge its efficiency, we evaluated the architecture using a physically motivated error model. It exhibits loss tolerance comparable to existing all-photonic architecture but without the need for intricate linear-optical resource-state-generation modules that conventionally rely on resource-intensive multiplexing. The versatility of the architecture also offers uncharted avenues for further advancing performance standards.

自旋光量子计算架构


我们引入了一种专为容错量子计算而设计的适应性强的模块化混合架构。它结合了量子发射器和线性光学纠缠门，以利用基于物质和基于光子的方法的优势。该架构的一个关键特征是其实用性，其基础是使用经过实验验证的光学组件。我们的框架能够执行任何量子纠错代码，但特别是通过利用远程光链路的内置非本地连接来保持低密度奇偶校验代码的可扩展性。为了衡量其效率，我们使用物理驱动的错误模型评估了该架构。它表现出与现有全光子架构相当的损耗容限，但不需要传统上依赖资源密集型复用的复杂线性光学资源状态生成模块。该架构的多功能性还为进一步提高性能标准提供了未知的途径。
