The world's first quantum communication commercial trunk line, the Shanghai-Hangzhou trunk line, was officially launched in the near future, and will realize the quantum security level voice telephone, video telephone and file transmission services between Hangzhou and Shanghai. This is the news obtained from Zhejiang Shenzhou Quantum Communication Technology Co., Ltd., which is the contractor of the trunk line and the enterprise within the city science and technology creation park.
Quantum communication has great application value and prospects in the fields of military, defense, finance and other information security, and the market capacity is huge in the future.
It is understood that the Shanghai-Hangzhou Quantum Communication commercial trunk line has a total length of 260 kilometers and a total investment of 170 million yuan. It passes through Shanghai Ruipu Road, Caohejing, Dagang, Jiaxing East, Tongxiang and Hangzhou.
"Because the single photon as the information carrier is inseparable and the quantum state is not cloned, it can realize the key distribution against any eavesdropping, and thus can ensure that the content encrypted with it cannot be deciphered." Qian Xin, executive vice president of Zhejiang Shenzhou Quantum Communication Technology Co., Ltd. It is said that in addition to absolute security, quantum communication has the advantages of large capacity and fast speed. In theory, it can transmit an unlimited amount of messages. Quantum communication will permanently change the cryptography, and the mass of government departments and enterprises between Hangzhou and Shanghai. Information will come and go, and it is "unconditional" security.
The head of the Information and Communication Development Department of the Ministry of Industry and Information Technology said that the Shanghai-Hangzhou Quantum Communication Commercial Trunk Line, as the world's first quantum communication commercial trunk line, marks the arrival of the quantum communication industrialization era and kicks off the market-oriented operation of the quantum communication industry. At present, the Shanghai-Hangzhou trunk line operators are engaged in active business negotiations with government departments, banks and enterprises. Qian Xin said that in the future, the trunk line will be connected to the Quanzhou-Beijing-Shanghai trunk line, and more regional trunk lines and trunk lines will be connected to become a quantum communication network. On this basis, the Quantum Communication Metropolitan Area Network of each place will access the trunk line and gradually form a quantum communication network extending in all directions.
As a cutting-edge technology related to national information and national defense security, quantum communication has been officially written into the national “13th Five-Year Planâ€. The construction of Shanghai-Hangzhou Quantum Commercial Main Line will form a Shanghai-Hangzhou wide-area quantum communication network, which will create conditions for value-added service models and profit mechanisms with quantum communication security applications as the core, which can attract more upstream and downstream investment in the industrial chain and promote quantum communication. The industrialization process in Zhejiang.
Relevant experts said that the Shanghai-Hangzhou Quantum Commercial Main Line will build China's first high-security communications backbone network covering a wide range of important industries and departments such as government affairs, business, finance, and electric power, and connecting Shanghai and Hangzhou, which will help accelerate the industrialization of quantum communication. To build a quantum communication industry cluster is of great strategic significance for promoting Zhejiang's economic transformation and upgrading, seizing the commanding heights of the quantum communication industry, and cultivating high-tech industries and growth engines.
