According to CCTV news reports, China’s first commercial quantum private communication network “Jinan Party and Government Organization Quantum Communication Special Network†was reviewed by experts in Jinan on the 12th, and the confidentiality, security, and code rate tests all met the design goals. Completed the acceptance of the entire network and officially put into use.
According to evaluation experts, the quantum communication part of the private network, the traditional network part, and the management system part have all met the original design requirements.
This is also the world's largest and most versatile quantum communication metropolitan area network. Its use is a landmark achievement in the quantum communication industry in China and even in the world.
Quantum is the most basic and indivisible unit of energy. Unknown quantum states cannot be accurately cloned. As long as someone tries to copy it, it will generate a bit error and it will be discovered. These characteristics make the quantum state communication absolutely safe in the transmission process.
Communication between all users of the Quantum Communication Network in Jinan's party and government agencies achieved at least 4,000 keys per second for data protection.
China has gone far ahead in the world in quantum communication technology research. In August 2016, the world’s first quantum science experimental satellite “Mozi†independently developed by China was successfully launched.
In June of this year, the scientific research team took the lead in the successful implementation of the two-dimensional quantum entanglement distribution of thousands of kilometers in the "Mozi", and fulfilled a quantum mechanical nonlocality test that satisfies "Einstein's locality conditions" on the spatial scale.
