An Analysis of State-of-the-art and Foreground of Quantum Communication Technology
XU Xiao-fan
Quantum Communication technology, which achieved many unprecedented breakthroughs in the past several years,is arousing the attentions from related authoritative bodies and the field of communication research with its particular characteristic of perfect security in information transmission. Firstly, in this paper, the course of development and milestones of quantum communication theory and technologies are reviewed. And the state-of-the-art of domestic and foreign quantum communication technologies are summarized, with the conclusion that the technology tends to be mature, and China stands in the front row of the world both in quantum communication theory and experiments. Then, the definition and model of the ideal quantum communication system are discussed and engineering scenarios of quantum communication system based on optical fiber channel and free space optical channel are provided. The security and communication ability now achieved by these scenarios are analyzed, drawing such conclusion that quantum communication technologies has both high practical value and broad development space. Finally, realistic application scenarios and future application prospect of quantum communication technology are presented, in consideration of the requirements and current technology levels.
