: Quantum computing is mostly confined within a single box and able to achieve computational performance of a limited number of qubits. As any classical computing system its scalability will fundamentally depend on dynamically interconnecting many qubit processing blocks to increase qubit count worth of computation. Also, quantum computing will have to interface and interconnect with classical computing systems in a data centre environment.The project will design and prototype one of the critical building blocks for distributed quantum and classical computing, the optical switch. We will explore theoretically and develop experimentally switching technologies aiming to deliver key characteristics for quantum and hybrid quantum+classical compute networked systems; very low loss, very low noise / high extinction ratio and fast reconfiguration.The project will also simulate and model how the switching can be used to form network systems to create distributed quantum and classical computing.It will formalise and parameterise the requirements as well as explore the dependencies between technologies (photonic quantum processors, heterogeneous computing, interconnects), distributed computing tasks (such as collective operations), quantum information transfer methods (quantum teleportation via photon entanglement) and networking to identify performance (entanglement rate, fidelity, scalability) and operational limits.

量子计算主要局限于单个盒子内，并且能够实现有限数量量子比特的计算性能。与任何经典计算系统一样，它的可扩展性将从根本上取决于动态互连许多量子位处理块以增加量子位计数的计算价值。此外，量子计算必须与数据中心环境中的经典计算系统进行接口和互连。该项目将设计和原型化分布式量子和经典计算的关键构建模块之一，即光开关。我们将从理论上探索和实验上开发开关技术，旨在为量子和混合量子+经典计算网络系统提供关键特性;损耗非常低，低噪音/高消光比和快速重新配置。该项目还将模拟和建模如何使用开关来形成网络系统，以创建分布式量子和经典计算。它将形式化和参数化要求，并探索技术（光子量子处理器，异构计算，互连），分布式计算任务（如集体操作），量子信息传输方法（通过光子纠缠的量子隐形传态）和网络之间的依赖关系，以确定性能（纠缠率，保真度，可扩展性）和操作限制。
