中文摘要：

研究了基于无相互作用测量的反事实量子通信方案。利用组合型马赫-曾德尔（M-Z）干涉仪对引入物体实现无相互作用测量,并利用其实现反事实通信,也即未借助实物粒子的信息传输。在弱相干场作为光源的情况下,从系统输出端的测量结果分析了组合型M-Z干涉仪一臂作为逻辑门的开关特性。通过对系统中大M-Z干涉仪和小M-Z干涉仪的个数选取,相应改变系统内部光学分束器的反射率,进而影响了两输出端口探测器所接收的光强之比。文章中给出了详细的理论推导过程。

英文摘要：

We proposed an protocol to study the interaction-free-measurement-based direct counterfactual quantum communication.the object can be able to ascertain without any interaction and the ideal counterfactuality quantum communication can be realized in interlink Mach-Zehnder interferometers（MZIs）,which in principle supplies the transfer of quantum information without transferring true photons.It is shown that the performance of switch as a logic gate on one of the interlink MZIs arms is inferred from measurements of outputs.The detection of the intensity ratio of the two final outputs is affected by both the number and the reflectivity of the beamsplitters in these MZIs.The detail theoretical derivation is presented in the paper.
