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.

In recent years, quantum communication has emerged as a game-changing technology with the potential to completely revamp the security architecture of the Internet. In this analysis, we look at the potential of quantum communication techniques to improve the safety of sent data and the effectiveness of networked data transmission. Examining well-known quantum communication protocols like BB84, E91, CV-QKD, and MDIQKD in light of their classical analogues is at the heart of this study. The research provides insight into the benefits and hurdles of using quantum communication in secure networking settings by studying a variety of performance measures, such as security levels, key rates, mistake rates, and communication lengths. We used an extensive analytical framework to compare the efficiency of the suggested quantum communication techniques to that of the original protocols. We conducted extensive experiments and analyzed the data to demonstrate the concrete advantages of using quantum communication for increasing security, increasing key rates, decreasing mistake rates, and increasing communication distances. Comparing the BB84 protocol's security grade of 0.98 to that of the conventional method's 0.92 reveals a 6.52 percent increase in safety. Key rates of 9.8 Mbps were achieved using the CV-QKD protocol, which was shown to be an improvement of 30.7% over the standard method's 7.5 Mbps.
