摘要

高精度时间同步是量子网络的基本要求。利用量子时钟同步，在卫星地面站对之间共享纠缠光子，模拟了一个全局时间分配网络。这在洲际尺度上提供了亚纳秒到皮秒级别的精度(优于GPS)。

Global Precision Time Distribution via Satellite-Based Entangled Photon Sources

High-precision time synchronization is a fundamental requirement for quantum networks. We simulate a global time distribution network by using quantum clock synchronization – sharing entangled photons between satellite-ground station pairs. This provides sub-nanosecond to picosecond level precision over intercontinental scales (better than GPS).
