Abstract
Review of Quantum Communication Network Topologies
Incoming article date: 22.07.2024the article considers the development trends of the high-tech industry of quantum communications. The most popular topologies of quantum communication networks are described, including those with trusted intermediate nodes. The methods of interaction between nodes of the backbone quantum-cryptographic network are given and the main methods of ensuring secure transmission in such networks are presented. A simplified scheme for distributing a quantum secret key between the end segments of the backbone telecommunication network using trusted intermediate nodes is considered. Possible data leakage channels in the general structure of quantum-cryptographic networks are described.
