基于三对Bell态纠缠交换的QDKD方案
QDKD Based on Three Pair of Bell State Entanglement Swapping
摘要
Abstract
A quantum deterministic key distribution is proposed based on three pair of Bell state entanglement swapping. Three pairs Bell state are entangled and measured by Bell measurement, information about deterministic key is transmitted via classic channel,any eavesdropper could be found in time. Compared with QDKD based on two pair of Bell state entanglement swapping,three pairs Bell state are used and two ways are designed to distribute deterministic key. Analysis results showed that only entanglement state of two particles is used and any unitary operation isn’t involved,it’s simple to operate and has high distribution efficiency.关键词
