Research Report on the development and application of quantum information technology

Quantum information technology represented by quantum computing, quantum communication and quantum measurement may lead to subversive innovation and reconstruction of information technology system, and give birth to revolutionary applications that change the rules of the game, so as to promote the evolution of information and communication technology and the breakthrough development of digital economy industry. In October 2020, Xi Jinping general secretary made a series of important instructions to grasp the general trend of quantum science and technology and play the first chess in the 24th special collective study of the Political Bureau of the CPC Central Committee, which provided strategic guidance and fundamental guidance for accelerating the development of China’s quantum information technology. In March 2021, the “14th five year plan” was officially released, which clearly put forward a series of plans and arrangements in the field of quantum information, such as establishing a national laboratory, implementing major science and technology projects, planning and distributing future industries, and strengthening cross innovation of basic disciplines.

In recent years, scientific research exploration and technological innovation in the three major fields of quantum computing, quantum communication and quantum measurement have been continuously active, there are many highlights of representative research results, the exploration of application scenarios has been widely carried out, and the cultivation of industrial ecology is in the ascendant. China’s quantum information technology field has a good foundation for research and application practice. The overall development trend of the three fields is good. It is expected to further achieve new achievements in technology research, application exploration and industrial cultivation in the future.

The Research Report on the development and application of quantum information technology issued by China information and Communication Research Institute for three consecutive years has been widely recognized by the competent authorities and industry experts. In order to continuously track, study and judge the overall development trend of quantum information technology, research and application progress and hot issues in the three fields, as well as technology evolution and application prospects, we have organized research and prepared the 2021 version of Research Report on development and application of quantum information technology for industry reference.
