Wang Yanan ice report
the project is organized by the Shandong Institute of information and communication technology. It is planned to be completed by the end of June 2013. After completion, it will become the largest metropolitan quantum communication network in the world. It is also the first large-scale test network in the world to fully carry practical application as the design target. Quantum communication, known as "absolutely safe" communication, is the frontier of international scientific research. The Shandong Institute of Quantum Communications Co., Ltd. specifically undertakes the industrialization of this project, and its general manager and chief engineer, Zhao Yong, said that the quantum key has an inseparable and unreplicable feature. Any attempt to intercept or test the quantum key will change the quantum state. Only the two ends of the communication can obtain this unconditionally and safely. A key, which fundamentally guarantees the non eavesdropping and non - deciphering of communication, is the only communication system known by human beings with the "information - Theory" security proof.
quantum communication is recognized by the world as a strategic research field that concerns national information security, contains major industrial needs and changes, and will lead to changes in the fields of e-government, electronic commerce, electronic medical treatment, and biometric transmission. In recent years, our province has actively planned the industrialization of quantum communication technology. In recent years, we have reached strategic cooperation with the Chinese Academy of Sciences and China Science and technology, and promoted the technology to fall to the ground in Shandong. And the construction of the Ji'nan quantum communication test network is listed in the first batch of provincial strategic new industrial projects.
Zhao Yong told reporters that at present, the company has the ability to make quantum communication technology practical and industrialized. Not long ago, the company established a small quantum dense telephone network based on quantum secure high speed data transmission for an important conference in China. It provided 7 * 24 hours of zero fault communication guarantee for the conference by using existing telephone seamless access.
"we want to launch the application like 'seed," Zhao Yong said. At present, 3 backbone nodes of the Ji'nan quantum communication test network backbone network have been built, and 50 practical nodes are designed according to the user's needs. The first batch of user node units have more than twenty, covering government, finance, political law, and section. Research, education and other five major fields. After the completion of the
trial network, it will provide high security telephone communication and network communication services for the subscriber units based on quantum communication. At the same time, the trial network will also serve as the core support project of the Ministry of science and technology in the theme of quantum communication. Next, in the construction of the national ground wide area wide area optical fiber quantum communication Beijing Shanghai trunk line, Ji'nan quantum communication test network will be used as the metropolitan access network to complete a variety of large scale, cross domain quantum communication core application and demonstration.
