We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and multiple ground stations located in Xinglong, Nanshan, and Graz, which establish satellite-to-ground secure keys with ∼kHz rate per passage of the satellite Micius over a ground station. The satellite thus establishes a secure key between itself and, say, Xinglong, and another key between itself and, say, Graz. Then, upon request from the ground command, Micius acts as a trusted relay. It performs bitwise… 

Satellite-relayed intercontinental quantum network

This thesis shows that quantum communication could be an ideal method to realize encrypted communication, although the thesis is only based on the simulation of the satellite-relayed quantum network and the channel noise still destroys some part of the decoded picture, thus more practical testing should be done to confirm this theory and some advanced methods should be used to reduce theChannel noise.

Robust aperiodic synchronous scheme for satellite-to-ground quantum key distribution.

A novel aperiodic synchronization scheme that can achieve high-precision time synchronization by encoding time information into pseudo-random laser pulse positions is proposed, resulting in a synchronization precision of 208-222 ps even when 90% of the light signals are lost.

Approaches to scheduling satellite-based quantum key distribution for the quantum network

This work develops a comprehensive framework integrated with precise orbital modelling and a cloud statistics model to enable a preassessment of satellitebased QKD applications and considers a network in which a space-based relay, the Micius satellite, executes a sequence of key delivery missions, allowing any two cities to have a shared key.
