Analysis of Quantum Key Distribution Protocols in Hybrid Quantum-Classical Optical Network
Quantum key distribution (QKD) networks are designed to allow multi-users for a dynamically anyto-any security communication. In this paper, three quantum key distribution schemes, compatible with classical optical networks, for future HQC networks are proposed and compared. For small-to-moderate size network, the highest secret key generation rate is supported by the prepare-measure scheme and the longest security distance is offered by entanglement-based scheme. For large networks, measurement-deviceindependent QKD, which is less demanding end-user technology and offers the best key rate, is the most proper solution for a cost-effective and reliable network deployment.
