The world's first micro -nano -quantum satellite "Jinan No. 1" successfully launched

At 12:12 on July 27, 2022, the world's first quantum micro -nano satellite "Jinan No. 1" was successfully launched in the Jiuquan Satellite Launch Center. At present, "Jinan No. 1" has entered the established track, solar windsurfing has been successfully opened, and it is about to carry out on -orbit testing. The successful development of the "Jinan No. 1" quantum micro -nano satellite will enable my country to realize the real -time star quantum key distribution based on the micro -nano -satellite and miniaturized ground station for the first time in the world to build a low -cost, practical world integration Quantum confidential communication network.

The "Jinan No. 1" micro -number satellite is led by the Hefei National Laboratory, and the Chinese University of Science and Technology, Jinan Institute of Quantum Technology, the Chinese Academy of Sciences Micro Satellite Innovation Research Institute, and Shanghai Institute of Technology Physics and other units. With the support of the Jinan High -tech Zone Management Committee, the Jinan Quantum Technology Research Institute is responsible for organizing the development of ground application systems as a user generally conducting verification of quantum key distribution application technology.

On the basis of the "Mozi" quantum scientific test satellite research and development and experiments, the research team successfully tested low -cost miniaturized quantum key distribution technology and real -time key extraction technology, etc., and completes the stars and key distribution terminals, micro -micro -distribution terminals, micro -micro The development of the satellite platform to achieve the weight of the weight to about 1/6 of the Mozi. The frequency of light sources is about 6 times and the time-effectiveness of the key generation is increased by 2-3. Key distribution experiments and technical verification and application promotion.

"Jinan No. 1" quantum micro -nano satellite is successfully launched and runs in orbit. It will follow Jinan to carry out demonstrations of commercialized wide -area quantum communication network application through small satellite ground stations in Jinan, which will help my country expand in the international international quantum communication field internationally. Leading positions to achieve national information security and information technology levels.
