摘要: The Micius satellite was successfully launched on 16 August 2016, from Jiuquan, China, orbiting at an altitude of about 500 km. The main scientific goals, including satellite-to-ground quantum key distribution, satellite-based quantum entanglement distribution, ground-to-satellite quantum teleportation, and satellite relayed intercontinental quantum network, were achieved in 2017. As a starting point, the Micius satellite has become a platform for quantum science experiments at the space scale. Here, we introduce the latest experimental achievements (in 2018-2020) based on the Micius satellite.Abstract: The Micius satellite was successfully launched on 16 August 2016, from Jiuquan, China, orbiting at an altitude of about 500 km.
