在分析高维Bell态纠缠交换基本性质的基础上,提出不需要任何酉操作、具有通用性和一般性的高维确定性安全量子通信方案.利用高维Bell测量的结果,发送方和接收方分别进行模加、减运算即可编码、解码信息.构造了两组互补的基,并根据其互补性质,提出了检测高维量子信道是否安全的方法.详细分析了几种常用攻击策略,并计算了这些攻击所引起的错误率,进而推导出通信双方需设定的错误率阈值的上界.
Based on the analysis of the basic properties of entanglement swapping in high-dimensional Bell states, a high-dimensional deterministic secure quantum communication scheme without general unitary operation and generality is proposed. Using the results of high dimensional Bell measurements, the sender and receiver Respectively modulo add and subtract operations to encode and decode information.Two groups of complementary bases are constructed, and according to their complementary properties, a method to detect whether the high dimensional quantum channel is safe is given.Several commonly used attack strategies are analyzed in detail The error rate caused by these attacks is calculated and the upper bound of the error rate threshold to be set by both communication parties is deduced.
