We present a programme for establishing the space worthiness of highly-miniaturised, polarisation-entangled, photon pair sources using CubeSat nanosatellites. Once demonstrated, the photon pair sources can be deployed on more advanced satellites that are equipped with optical links to establish a global space-based quantum key distribution network. In doing so, this work will also bring experimental tests of the overlap between quantum and relativistic regimes closer to realisation.

纳米卫星实验可实现未来的天基QKD任务

我们提出了使用CubeSat纳米卫星建立高度微型化，偏振纠缠的光子对源的空间价值的程序。一旦证明，光子对源就可以部署在配备了光链路的更高级的卫星上，以建立基于天基的全球量子密钥分配网络。这样，这项工作还将使量子和相对论体系之间的重叠的实验检验更接近实现。
