The goal of this project is to develop a source of time/frequency-entangled photon pairs suitable for multipurpose quantum communications in daylight conditions the context of next generation wireless communications. The large background noise due to solar radiation limits satellite-to-ground and, in general, free-space entanglement distribution to night operation, strongly reducing the time of operation of quantum communications links. In this project, we propose to investigate integrated narrow-linewidth sources of entangled photons.The project will also explore the opportunities from flying the source on future Arqit satellites to validate it for future Quantum Communications networks and for entanglement distribution experiments with international partners for a variety of applications in the context of the future Quantum Internet.

该项目的目标是开发一种时间/频率纠缠光子对源，适用于日光条件下的多用途量子通信，即下一代无线通信。由于太阳辐射产生的大背景噪声限制了卫星到地面以及一般自由空间纠缠分布的夜间操作，大大减少了量子通信链路的操作时间。在这个项目中，我们计划研究纠缠光子的集成窄线宽源。该项目还将探索在未来的Arqit卫星上飞行源的机会，以验证它用于未来的量子通信网络，并与国际合作伙伴一起进行纠缠分发实验，用于未来量子互联网的各种应用。
