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.
