Mozi (Micius Satellite for Quantum Science Experiments) is the first experimental satellite of space quantum science developed by China.
The Mozi satellite project is under the overall responsibility of the National Space Science Center of China Academy of Sciences (hereinafter referred to as the "Space Center"). This satellite is one of the first scientific experimental satellites in the space science strategic pilot science and technology project of China Academy of Sciences. Its main scientific goal is to carry out high-speed quantum key distribution experiments between satellites and the ground, and on this basis, carry out wide-area quantum key network experiments.
In order to make a major breakthrough in the practical application of space quantum communication; The experiments of quantum entanglement distribution and quantum teleportation are carried out on the spatial scale, and the experimental study of the completeness test of quantum mechanics is carried out on the spatial scale.
2065438+On August 6th, 2006 1 40, China successfully launched the Mozi quantum science experimental satellite into orbit by the Long March II carrier rocket at Jiuquan Satellite Launch Center. In May, 2022, China Mozi Satellite achieved a new record of 1200 km surface quantum state transmission.
Scientific goal
This technological breakthrough not only enables China to directly provide high-security quantum communication guarantee to South China Sea islands, foreign embassies and consulates, China ocean-going ships and other areas that cannot be covered by optical fibers, but also provides reliable technical support for China to build a world-wide integrated quantum secure communication network in the future.
At the same time, quantum satellites carry out quantum entanglement distribution and quantum teleportation experiments on the spatial scale. Through the satellite-ground entanglement distribution of Mozi, quantum entanglement can be established between two ground stations which are more than 1200 kilometers apart at the speed of 1 pair/second, which will enable humans to conduct quantum science experiments on the spatial scale for the first time.
And make technical preparations for testing basic physics principles such as general relativity and quantum gravity in outer space in the future, which has become another important contribution of China to the world in the field of basic physics.
Quantum satellite is one of the first scientific experimental satellites in the space science pilot project of China Academy of Sciences. Its main scientific goal is to carry out high-speed quantum key distribution experiments between satellites and the earth, and on this basis, to carry out wide-area quantum key network experiments in order to make a major breakthrough in the practical application of space quantum communication.
The second is to carry out quantum entanglement distribution and quantum teleportation experiments on the spatial scale, and to carry out experimental research on the completeness test of quantum mechanics on the spatial scale.
