Quantum communications can secure data transmission, guaranteed by the laws of physics. Technology toachieve this based on encoding information on individual particles of laser light is proven over dedicated point-to-point links. However the full potential will only be realised with multi-user quantum networks, and it isimpossible to copy and resend quantum data, preventing traditional approaches. Quantum relays offer asolution, allowing quantum keys to be teleported across fibre-optic networks. Our vision is to construct andoperate such a quantum relay, for the first time using practical semiconductor technology at the commerciallyoptimum 1550 nm wavelength band. This will be an important step towards widespread adoption ofguaranteed network security solutions for businesses and customers alike.

量子通信可以确保物理定律保证的数据传输。在专用的点对点链路上证明了基于激光光的各个粒子的编码信息来完成的技术。但是，只有通过多用户量子网络才能实现全部潜力，并且不可能复制和重新构成量子数据，以防止传统方法。量子继电器提供ASOLUTION，允许在纤维光网络上传送量子键。我们的视野是首次使用实用的半导体技术构建和操作这样的量子继电器，以1550 nm的波长频段进行。这将是迈向广泛采用为企业和客户提供保证网络安全解决方案的重要一步。
