论文摘要
以高精度和准确性来衡量，保持和分配时间的能力是科学探索的基础能力。除了基本科学之外，时间同步是公共和私人通信，导航和范围以及分布式传感的必不可少的特征，以及其他技术应用。我们建议实现卫星和地面时钟的量子网络，以实现量子时钟同步到picsecond的精度。提议的QCS网络的实现提供了双重优势：（1）比当前可能可能的经典应用程序更准确，健壮且安全的时间同步网络，以及（2）一种资源来满足未来量子通信网络的更为严格的同步要求。
The ability to measure, hold and distribute time with high precision and accuracy is a foundational capability for scientific exploration. Beyond fundamental science, time synchronization is an indispensable feature of public and private communication, navigation and ranging, and distributed sensing, amongst others technological applications. We propose the implementation of a quantum network of satellite- and ground-based clocks with the ability to implement Quantum Clock Synchronization to picosecond accuracy. Implementation of the proposed QCS network offers a double advantage: (1) a more accurate, robust, and secure time synchronization network for classical applications than currently possible, and (2) a resource to fulfill the much more stringent synchronization requirements of future quantum communication networks.
