Quantum communications can guarantee the security of data transmission. Although the technology to achieve this isproven over dedicated point-to-point links, the full potential will only be realised with multi-user quantum networks.Quantum relays offer a platform which can provide this, allowing quantum keys to be teleported across fibre-optic networks.Commercial uptake requires practical entangled light sources operating within the optimum telecom wavelength bandaround 1550 nm, and thanks to an established InnovateUK funded project, such sources are emerging for the first time.Our vision is to construct and operate such a quantum relay, making practical quantum networks a realistic opportunity. Bycombining the proven expertise and experience of the partners together with a challenging workplan, we will create animproved generation of entangled photon-pair light sources engineered to interact with laser light. Epitaxial material will begrown at the University of Sheffield and processed into a range of novel device structures at the University of Cambridge. Aprototype quantum relay will be delivered by TREL, which will leverage our unique entangled light sources, to teleportquantum information encoded on laser beams, as demonstration of a practical quantum network.

量子通信可以保证数据传输的安全性。尽管在专用点对点链接上实现这一目标的技术，但只有多用户量子网络才能实现全部潜力。Quantum继电器提供一个可以提供此功能的平台，从而允许量子键在光纤上传达量子网络。商业摄取需要在最佳电信波长1550 nm内运行的实用纠缠的光源，并且得益于已建立的Innovateuk资助的项目，这种来源首次出现。我们的愿景是构建和操作这样的量子关系，使得量子中继，使其成为一种量子关系。实用的量子网络是一个现实的机会。弥补合作伙伴的可靠专业知识和经验以及具有挑战性的工作计划，我们将创建动画的一代纠缠的光子对光源，设计用于与激光光进行互动。外延材料将在谢菲尔德大学（University of Sheffield）繁殖，并在剑桥大学的一系列新型设备结构中进行处理。牙型量子继电器将由TREL传递，TREL将利用我们独特的纠缠光源，将链球菌信息用于在激光束上编码的链球菌信息，以证明实用的量子网络。
