Description

technical field [0001] The invention belongs to the quantum enhanced time synchronization technology, and particularly relates to a quantum enhanced remote clock synchronization method and system. Background technique [0002] Clock synchronization provides a unified time standard for parties working together on an activity under which their activities can be completed efficiently and accurately. Taking navigation activities as an example, time synchronization is especially important, because for fast-moving objects, the update rate of navigation data must match the speed of the moving object for effective navigation, and accurate matching of real-time navigation data must be based on the time synchronization of all parties. premise. The synchronization accuracy of traditional navigation clocks is limited by the bandwidth of classical electromagnetic wave signals, and the upper limit of accuracy is nanoseconds. It is difficult to achieve higher-precision navigation activiti...
