It was learned from the Chinese Academy of Sciences that my country’s first quantum science experimental satellite will be launched in July this year, which will be the first time in the world to achieve communication between the satellite and the ground.

Pan Jianwei, chief scientist of quantum satellites, professor at the University of Science and Technology of China, and director of the Center for Excellence in Quantum Information and Quantum Technology Frontiers of the Chinese Academy of Sciences According to the academician, the security of quantum communication is based on the basic principles of quantum physics. The indivisibility of single photons and the non-replicability of quantum states ensure that information cannot be eavesdropped and cannot be cracked, and in principle ensures identity authentication, transmission encryption and digital signatures, etc. Unconditional security can fundamentally and permanently solve information security problems.
According to reports, the quantum science experimental satellite project will develop and launch 1 quantum science experimental satellite and build 4 quantum communication ground stations and a space quantum science experiment system with a space quantum teleportation experimental station as the core. The satellite is equipped with payloads such as a quantum key communication machine, a quantum entanglement transmitter, a quantum entanglement source, and a quantum experiment control and processor. It has two independent sets of payload pointing mechanisms, which are controlled cooperatively by the attitude control and pointing system and can communicate with those on the ground. Two optical stations that are thousands of kilometers apart simultaneously establish quantum optical links.
After the launch of the quantum satellite, the space-ground integrated quantum science experiment system will be put into formal operation, including satellite-ground high-speed quantum key distribution, Wide-area quantum communication network, satellite-to-ground quantum entanglement distribution, and ground-to-satellite quantum teleportation and other scientific experimental tasks.

Pan Jianwei also revealed that the “Beijing-Shanghai Trunk Line” large-scale optical fiber quantum communication backbone network project is expected to be delivered in the second half of this year . This project will build a thousand-kilometer-level highly reliable, scalable, military-civilian integrated wide-area optical fiber quantum communication network, and build a large-scale quantum communication technology verification, application research and application demonstration platform. Combined with quantum satellites and the Beijing-Shanghai trunk line, my country’s wide-area quantum communication system integrating space and ground will be initially constructed.
As the third scientific satellite of the Chinese Academy of Sciences’ space science pilot project, the Quantum Science Experiment Satellite was officially established in 2011. After five years of development, the satellite has completed its final assembly and is undergoing the final round of power-on testing before leaving the factory. After passing the factory review, the quantum satellite will be transferred to the Jiuquan Satellite Launch Center in June this year.
