Abstract
As an important branch of modern information technology, the research background of quantum communication technology stems from the limitations of traditional communication mode in security and efficiency. This paper aims to explore the core principle and the potential application prospects of quantum communication, and analyze the key technologies such as quantum entanglement, quantum key distribution (QKD) and quantum teleportation, to reveal its unique advantages in information transmission. Using theory derivation and experimental verification to systematically evaluate the performance of quantum communication in eavesdropping resistance, data transmission rate and network scalability. The results show that the communication mode based on quantum mechanics can realize theoretically unconditionally secure information exchange and provide technical support for next-generation communication networks. The main innovation of this paper is an improved quantum key distribution protocol, which reduces the bit error rate and significantly improves the efficiency of key generation, and lays a foundation for practical engineering applications.
