The Principle and Prospect of Quantum Communication

Abstract

With the progress of science and technology, as well as the development of the times, people begin to have higher requirements on the security and efficiency of communication, so quantum communication has attracted much more attention. Quantum communication has lots of advantages such as unconditional security, high transmission efficiency, strong anti-interference ability and good concealment performance. In this paper, the author analyzes the advantages and the present situation of quantum communication. This paper briefly introduces the model of quantum communication network, the quantum computing, data decoding based on quantum computation and the quantum search algorithm concepts, which are described in simple terms. Two quantum secure direct communication protocols are also introduced and analyzed, and the prospects of quantum communication are presented.
