论文摘要
可以使用大型卫星机队在基于地面的节点之间分发纠缠的光子对,可以实现用于安全通信的全球量子网络。由于卫星的成本取决于其大小,因此最小的卫星将是最具成本效益的。本文介绍了在纳米 - 卫星上运行的微型,极化纠结的光子对来源。来源违反了贝尔的不平等,CHSH参数为2.6 $ \ pm $ 0.06。该来源可以与光学链路技术结合使用,以实现未来的量子通信纳米 - 卫星任务。
Global quantum networks for secure communication can be realised using large fleets of satellites distributing entangled photon-pairs between ground-based nodes. Because the cost of a satellite depends on its size, the smallest satellites will be most cost-effective. This paper describes a miniaturised, polarization entangled, photon-pair source operating on board a nano-satellite. The source violates Bell's inequality with a CHSH parameter of 2.6 $\pm$ 0.06. This source can be combined with optical link technologies to enable future quantum communication nano-satellite missions.
