Multi-user quantum key distribution model and the correlative protocol
摘要
Abstract
We propose a Multi-user Quantum Key Distribution (MQKD) protocol, which only needs n quantum channels for a communication system of n users to realize the protocol with entangled states and entanglement swapping. By the quantum mediator, any two among n users of the system can communicate with each other, even though there is no direct quantum channel between them. Based on the traffic theory, we present a relationship formula of the number of user n and the number of Bell state measurement units m. Because entanglement swapping entangles the quantum states of the two users, the quantum mediator has no way to fraudulently intervene in or eavesdrop on the communication.关键词
