The beijing-shanghai line will be built in large-scale optical fiber quantum communication backbone network

( Industry news] The beijing-shanghai line will be built large-scale quantum communication backbone fiber atltech P beijing-shanghai line will be built large-scale optical quantum communication backbone in the second half, the beijing-shanghai line will be built in large-scale optical fiber quantum communication backbone network. Recently, the CPPCC national committee, executive vice President of university of science and technology of China, member of jian-wei pan in an interview said. It is understood that this quantum lines linking Beijing and Shanghai, through the shandong jinan, hefei, anhui is thousand kilometers high confidence level, extensible wide-field optical quantum communication network, the world's first. After the completion of it will be widely used in areas such as finance, government affairs information security transmission. Quantum communication, the use of photon quantum state to load and transport information. In principle, quantum communication is an unconditional secure communication manner. Because of single photon as information carrier inseparable, quantum states cannot be cloned, can resist any hacking key distribution, and can guarantee the encrypted content cannot be deciphered. Metropolitan area of quantum communication network can be realized through the optical fiber, inter-city quantum network via relay connection, transfer to realize long-distance quantum communications via satellite, eventually constitute a wide-area quantum communication network. Jian-wei pan said, the future can form the integration of the global optical quantum communications infrastructure, heaven and earth to form a complete quantum communication industry chain, and the next generation of national sovereignty in information security ecosystem building based on quantum communication security for the future of the Internet, namely 'quantum Internet'.
