A kind of improved quantum key distribution scheme

Abstract

Abstract In this paper, the problem on quantum key distribution (QKD) is discussed. Firstly, based on the framework of BB84 protocol and Heisenberg s uncertainty principle, a kind of QKD scheme is proposed; then, theoretical analysis is conducted to justify the QKD scheme; finally, some examples have been included, and the results show that the given QKD scheme not only inherits the simple and practical property from BB84, but also effectively reduces the resource loss, and possesses the better performance of monitoring eavesdropping.
