Research on Security and Electronic Countermeasure of Wireless Quantum Communication System

Haoming Wang, Zhao Weikang, Nan Li

With the successful launch of quantum communication satellite, the boom of wireless quantum research and application is rising all over the world, and the security of quantum communication has reached a new height in battlefield communication, but from an objective point of view, this is a misunderstanding of it. Based on this, this paper analyzes the structure of the quantum communication system, and on this basis, makes necessary distinctions between the security, effectiveness and reliability of the communication system. It points out that eavesdropping can still be realized by utilizing the defects of the wireless quantum communication engineering, especially the suppression and interference of wireless quantum communication transmission can greatly affect the effectiveness of communication. Finally, the electronic countermeasures method of wireless quantum communication is summarized through research, which has important reference significance for promoting the application and expansion of quantum countermeasures in electronic countermeasures.
