摘要: 文中抽出了在4维Hibert空间上的量子密钥分配算法,构造了三种测量基来应对能在两个量子比特上出现的所有错误,保证了窃听检测过程的有效性,从而提供了无条件安全性的根本依据,该协议的最大优势在于显著节省上了量子和经典信息的通信量。

Abstract: A novel quantum key distribution protocol is proposed in this paper, by constructing three different types of measurement bases. Such unusual construction guarantees that all possible errors occurred on two qubits can be detected, and provides the uncondi
