4粒子团簇态的可控隐形传态

为实现4粒子团簇态更加经济和安全的隐形传态,提出2种利用6粒子团簇态为量子信道的可控隐形传态方案,分别是3方参与的可控隐形传态方案和4方参与的可控隐形传态方案.在控制者同意信息传输的情况下,2种隐形传态方案成功的概率是一致的,为4|a|2,即选用最大纠缠的6粒子团簇态为量子信道时,传输成功率为100%.通过2种方案的对比发现,控制方的增多可以有效地提高信息传输的安全性,但同时会使接收方还原原始信息的操作更加复杂.

Controlled Teleportation of 4 Particle Cluster State

In order to achieve a more economical and secure teleportation of the 4 particle cluster state,two controlled teleportation schemes using 6 particle cluster states as the quantum channel are proposed.It is the three party involved in the controlled teleportation and the four party to participate in the controlled teleportation.The probability of success of the two schemes is consistent with the coordination of the control er,and the probability is 4|a|².The successful transmission rate is 100% when the 6 particle cluster states of the maximal entanglement are used as the quantum channel.Through the comparison of the two schemes,it is found that the increase of the control side can effectively improve the security of information transmission,but also make the operation of the receiver to restore the original information more complex.
