Abstract: The Quantum Science Experiment Satellite is one of the four science experimen satellites in the first phase of space science pilot project of CAS. It is also the first satellite in the world to be used for the space quantum communication experiments. This project aims to establish a long distance quantum experimental platform between the satellite and ground stations, and to complete a series of space scale quantum communication experiments. In August 16, 2016, ˇ°Moziˇ± was successfully launched, which laid an important foundation for the space-earth integrating large-scale quantum science experimental platform. The content of this report includes:
1. The science goals of the ˇ°Moziˇ± Satellite are introduced, including quantum key distribution (QKD) from the satellite to ground, the wide-area quantum communication network demonstration, quantum entanglement distribution from the satellite to two ground stations to test Bellˇ®s inequality, and quantum teleportation experiment from ground to satellite to test the feasibility of the long distance quantum teleportation.
2. The engineering missions of the ˇ°Moziˇ± Quantum Science Experiment Satellite, the space-earth integrating system and the main technical specifications of the satellite platform are introduced. During the development of the project, many key technical problems had been solved, and we had made great progress in the space optics including the high precision optical tracking and pointing between the satellite and ground stations, the near-diffraction-limited optical system for photon emission and detection, the polarization state maintaining and polarization vector benchmark tracking technologies, the single photon detection technology in space, and the composite satellite attitude control technology, etc.
3. The in-orbit tests and results of the quantum satellite are presented. The test data shows that all the performance parameters have reached or exceeded the expected requirements, whether in optical tracking and pointing, near-diffraction-limited light emission, polarization state maintaining, single photon detection or composite satellite attitude control. By the time of August, 2017, all the science goals have been successfully completed.
