China's quantum satellite completes space-ground link system

China's quantum satellite, Micius, has established space-ground link systems (SGLS) with four ground stations so far, the Chinese Academy of Sciences announced on Wednesday.

Micius, the world's first quantum satellite, has successfully established SGLS with ground stations in Beijing, Xinjiang Uygur Autonomous Region, Qinghai Province and Tibet Autonomous Region, the chief scientist of quantum satellite program, Pan Jianwei, said at a press conference in Beijing on Wednesday.

He said that the quantum satellite has also completed platform testing and load testing, as well as tracking and pointing tests.

Currently, the satellite is undertaking parameter adjustment and data accumulation. It is expected to complete all in-orbit experiments by mid-November.

Micius was launched from the Jiuquan Satellite Launch Center in northwest China's Gobi Desert on August 16, 2016. It will carry out three main scientific experiments: secure key distribution between satellite and ground, quantum entanglement, and quantum teleportation. — Reuters
