Optical Switching And Networking For Quantum And Classical Data Centers

：量子计算大多局限于单个盒子内，能够实现有限数量的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依赖于动态互联多个量子比特处理块来增加量子比特计数的计算量。此外，量子计算必须在数据中心环境中与经典计算系统对接和互连。该项目将设计和制作分布式量子和经典计算的关键构件之一--光开关。我们将从理论上探索和实验开发交换技术，旨在为量子和混合量子+经典计算网络系统提供非常低的损耗、非常低的噪声/高消光比和快速重新配置的关键特征。该项目还将模拟和建模如何使用交换来形成网络系统，以创建分布式量子和经典计算。该项目将形式化和参数化需求，并探索技术(光子量子处理器、异质计算、互连)、分布式计算任务(如集体操作)、量子信息传输方法(通过光子纠缠进行量子隐形传态)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。

: 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.
