一个11比特的三方量子隐形传态方案

An 11-qubit tripartite quantum teleportation scheme

利用量子纠缠态特性提出一个11比特的量子隐形控制传态方案。Alice、Charlie和Edison分别选择合适的测量基,对与之对应的粒子态(a,1)、(b,2)、(c,3)、(d,4)和(e,5)进行投影测量,测量结束后,将结果分别告知控制者Gaia和对应的接收者Bob、David和Ford,然后每个接收者根据测量的结果选择与结果对应幺正变换操作,即可恢复到发送时候的初始状态,完成此次传输。经过计算与验证,方案的成功率为100%,传递效率为22.73%。

A new quantum-controlled teleportation scheme by using eleven-qubit entangled state is proposed.Alice,Charlie and Edison select the appropriate measurement basis respectively,and measure the corresponding particle states(a,1)(b,2)(c,3)(d,4)and(e,5).After the measurement,the results are respectively told to the controller Gaia and the corresponding receivers Bob,David and Ford.Then,the corresponding unitary transformation operation is selected by each receiver according to the measurement results.The initial transmission status is restored and then the transfer is completed.After verification and reasoning,this scheme can reach 100%success rate and 22.73%transmission efficiency.
