On February 1st, ICBC Beijing Branch successfully used the quantum communication technology in the intra-city encryption transmission of its electronic archive. It is the first successful application of quantum technology in the Chinese banking industry, marking a new level of information security technology in China’s banking sector.

According to an official with ICBC, to further enhance information security, ICBC has implemented “Beijing-Shanghai Verification and Application Demonstration Project of Quantum Encrypted Communication Technology” together with the University of Science and Technology of China. Meanwhile, the Bank has launched financial application of the quantum technology in intra-city communication of Beijing and Shanghai as well as the thousand-km-level communication between the two cities.

Quantum is a status of microscopic particle. Data information composed of quantum dots is free from external interception or copying during transmission. Quantum communication is by far the only strictly testified technology that can guarantee the unconditional communication security from its principle. It has significant application value and prospect in various fields such as national defense and financial information security, and is regarded as an important technology foundation for safeguarding communication security in future information society. China has a leading position in the world in terms of quantum communication with a sizable experiment network of quantum communication. The “Beijing-Shanghai Verification and Application Demonstration Project of Quantum Encrypted Communication Technology” has been officially launched, with the aim to build a Beijing-Shanghai quantum communication route of over 2,000 km connecting Beijing, Jinan, Hefei and Shanghai as well as a metropolitan access network, which can serve the confidential transmission of governmental information and financial business information.
