我们提出了一种确定性通信协议，该协议不使用纠缠。它在双向量子信道中利用非正交态来实现无条件安全性和高传输效率。我们明确表明，无论信道上的噪声如何，该方案对于一类个体攻击是安全的。利用现有技术，它的实验实现是可行的。
We propose a protocol for deterministic communication that does not make use of entanglement. It exploits nonorthogonal states in a two-way quantum channel to attain unconditional security and high efficiency of the transmission. We explicitly show the scheme is secure against a class of individual attacks regardless of the noise on the channel. Its experimental realization is feasible with current technology.
