At
16:20 on August 16, 2016, China's Jiuquan Satellite Launch Center in
the Long March II Ding launch vehicle successfully the world's first
quantum scientific experimental satellite "Mozi" launch. This will enable China in the world for the first time between the
satellite and terrestrial quantum communication, the construction of the
integration of the world of quantum communication and scientific
security experimental system.
Quantum
satellite chief scientist, Chinese Academy of Sciences Pan Jianwei
introduction, the security of quantum communication based on the basic
principles of quantum physics, single photon inseparability and quantum
state can not be copied to ensure that information can not be
eavesdropping and unbreakable, in principle to ensure identity Authentication, transmission encryption and digital signatures, such
as unconditional security, can be fundamentally, permanently solve
information security issues.
Quantum
satellite in December 2011 project, is the Chinese Academy of space
science pilot special first scientific experiment satellite. Its
main scientific goal is to carry out experiments on quantum-key
distribution of high-speed satellite and ground, and to carry out
wide-area quantum key network experiment on this basis, with a view to
achieve a quantum breakthrough in the practical application of space
quantum communication; the second is quantum entanglement Distribution, and quantum teleportation experiments, validating the quantum mechanics theory at the spatial scale.
The
ground science application system including Nanshan, Delingha,
Xinglong, Lijiang, and the Quantum Satellite Teleportation Experiment
Station is also built, and together with the quantum satellite,
constitute the integrated system of quantum and scientific experiments.
