Quantum Secure Primary Communication Based on Quantum Information Compression

Abstract

The need for information compression has become critical , particularly in quantum secure communication. It is presented a quantum secure primary communication with information compression. Quantum information can be divided into effective information and channel detection information improve transmission efficiency. The sending node will transmit effective information compressed in advance and channel detection information which are preprocessing by single photon to the receiving node. Meanwhile, the sending node will disclose the relevant content of channel detection information and check the security of quantum channel. If the channel is safe, the sending node will transmit the effective information decoding content to the receiving node. In process, the initial length of quantum information and the corresponding complexity of information as criteria of transmission efficiency, calculate and select the requirement compressed information to improve the transmission efficiency as far as possible. Then, it developed the simulated with MATLAB to calculate the relationship between transmission speed and compression length. In addition, it analyzes the security of communication protocol. The protocol has practical significance in improving the transmission speed from two aspects which are improving the transmission efficiency of quantum information and completing the whole communication process in one step.
