Method of synchronization in quantum network

摘要

In the quantum network synchronization method according to the present invention, the method is performed by a first device, which is a transmitting device, and transmits time information to a second device, which is a receiving device, through a classical channel and a quantum channel A time synchronization step of performing time synchronization with the second device through transmission; And a frequency coordination process for communicating with a standard clock through a phase stabilized link to perform frequency synchronization, and performs time synchronization using time information between the devices in the quantum network .
