According to the latest news on the 16th, at 1:40 a.m. on August 16, 2016, Chinese scientists successfully launched the world's first quantum scientific experimental satellite, the Mozi, at the Jiuquan Satellite Launch Center with the Long March II Ding carrier rocket. It has successfully entered orbit. This made our country the first country in the world to realize quantum communication between space and the earth. At the same time, it also built a quantum and confidential communication and scientific experiment system integrating heaven and earth in China. It is reported that the "Mozi" is the world's first quantum scientific experimental satellite. Pan Jianwei, chief scientist of Quantum Satellite and an academician of the Chinese Academy of Sciences, said that the reason why it was named “Mozi†was because Mozi first discovered that light travels in a straight line through small hole imaging experiments, and he also proposed a kind of “particle theoryâ€. ". According to Pan Jianwei academician, the security of quantum communication is based on the basic principles of quantum physics. The inseparability of single photons and the non-reproducibility of quantum states ensure that information cannot be eavesdropped and cannot be cracked. In principle, identity authentication, transmission encryption, and digital are ensured. Unconditional security such as signatures can fundamentally and permanently solve information security problems. The quantum satellite project was established in December 2011 and is one of the first scientific experimental satellites for space science pilots of the Chinese Academy of Sciences. Its main scientific goal is to conduct high-speed quantum key distribution experiments on Xingdi and carry out wide-area quantum key network experiments on this basis, with a view to achieving a major breakthrough in the practical application of space quantum communication; secondly, it also hopes to implement quantum on the spatial scale. Entangled distribution and quantum teleportation experiments to verify the theory of quantum mechanics. Pan Jianwei said that China’s self-developed quantum satellites have broken through a series of key technologies, including high-precision tracking, star polarization preservation and basis vector correction, and satellite-borne quantum entanglement sources. The successful launch of quantum satellites and on-orbit operation will help China maintain and expand its international leading position in the practical application of quantum communication technology, and achieve a leap-forward improvement in national information security and information technology level, which is expected to promote the quantum scientists in China. The major breakthroughs in the frontier areas are of great significance in promoting the sustainable development of our space science satellite series. This mission also carried a launch of the Chinese Academy of Sciences developed a thin atmospheric scientific experimental satellite and the Spanish scientific experimental small satellite. After the quantum satellite launches into orbit, it will conduct in-orbit testing for about three months and then move to orbit.
