电力系统中量子信息学的应用现状及展望

The quantum informatics has unique advantages in information acquisition, transmission and processing, etc., and has great potential in ensuring information security of new power systems and alleviating computational difficulties. In this paper, the research status of quantum informatics in the context of power system applications is summarized from two aspects of quantum communication and quantum computing, and the possible research directions in the future are prospected. First, the basic concepts and principles of quantum informatics are introduced. Then, for quantum communication, the applicability of representative quantum communication technologies in new power systems is analyzed. The research status of quantum communication in power systems is generalized in four aspects: long-distance information transmission, multi-user communication, unified standards and dedicated research platforms. For quantum computing, the basic principles of quantum computing methods and their research status in power systems are summarized from the aspects of linear algebraic operations, optimization problem solving, machine learning and parameter estimation. Finally, the application of quantum informatics in new power systems is prospected, and the development suggestions of quantum informatics in power systems are put forward.
