提出基于Cluster态量子对话,这使得合法双方可以直接交换4位秘密信息.和3粒子W态相比较,此协议有以下优点:经过两步安全检查后,通过单光子发射和两位经典信息的帮助,可以相互传输4比特秘密信息.还可以克服拦截重发攻击、纠缠测量攻击和最优化非相干攻击.
Cluster state quantum dialogue is proposed,which enables both legitimate parties to exchange their 4 bit secret messages in a direct way.Compared with the there-particle W states,the shemes have following advantages.After two-step security check,four-bit secret message can be transmitted to each other by transmitting of single particle with the aid of two-bit classical information.The scheme can discard the drawback of the intercept-resend attack,the entangle-measure attack,and the optimal incoherent attack.
