Quantum communication can be used to build an indecipherable key system, so quantum communication has become the forefront of science and technology in today's world. Because of its advantages such as absolute secrecy, large communication capacity and fast transmission speed, it can complete special tasks that classical communication cannot complete in the military field. Quantum communication uses quantum states as information elements to realize the effective transmission of information. It is another revolution in the history of communication after telephone and optical communication. Therefore, this paper discusses the research status of military communication applications of quantum technology.

Cryptographic technique is the core of information security technology.The three cryptosystems(symmetry,no-symmetry and vernam) and quantum cryptography's theory and recent technology were introduced.Limitation of the classic cryptography communication was analyzed,and security of the quantum cryptography was given in this paper.
