Overview of Technology Research in Quantum Communication System

Abstract

As the established communication networks no longer meet people’s need in the speed and the security in transferring information, quantum communication draws people’s attention. Taking advantage of the basic quantum properties, quantum communication guarantees the message being delivered promptly and safely. This paper first introduces a general background quantum communication. After that, we introduced the history of the development of quantum communication and Quantum Key Distribution (QKD) as well as the general flow of quantum communication. Based on that, we evaluated a scheme of quantum communication network based on QKD, proposing different methods to improve the security and efficiency of the transmission of information. We encapsulated the history of the development of QKD. We conclude that the improvement of quantum communication depends on the algorithms. While various algorithms are proposed, we discussed a potentially possible way to combine the advantages of the algorithms. However, the actual effectiveness of our method still needs to be testified in future researches.
