Abstract

Quantum communication networks, as a critical component of next-generation information technology, leverage the fundamental principles of quantum mechanics to achieve secure information transmission through the properties of quantum states. This paper aims to explore the basic principles and application scenarios of quantum communication networks by analyzing core technologies such as quantum key distribution and quantum teleportation, in conjunction with practical application requirements, to investigate their feasibility in network construction. Through an examination of relevant research both domestically and internationally, employing a combination of theoretical analysis and case studies, this study delves into the potential applications of quantum communication networks in fields such as finance, military, and government services. The findings indicate that quantum communication networks can provide unconditionally secure information transmission, effectively resisting eavesdropping attacks, thereby demonstrating significant advantages over traditional communication methods. This paper innovatively proposes a quantum relay scheme suitable for large-scale networking and systematically analyzes existing technological bottlenecks, providing theoretical foundations and technical support for the practical development of future quantum communication networks. The results suggest that quantum communication networks not only play a crucial role in specific domains but also hold the potential for broader civilian market promotion, potentially becoming a key technological support for constructing the next generation of information security systems.
