任意未知三粒子纠缠态的概率传递及其量子逻辑电路

Probabilistic Teleportation and Guantum Logical Circuit of an Arbitrary Three-particle Entangled State

提出了一种任意未知三粒子纠缠态通过三对部分纠缠态作为通道的概率传递方案.在贝尔态测量后,如果接收者引入一个联合幺正变换,传递可以顺利实现.不同于其他文献之处在于,这个联合幺正变换对于所有情况是惟一的.最后,给出了实现这种传递的量子逻辑电路.

This paper presented a scheme to probabilistically teleport an arbitrary and unknown three-particle enmeasurements, an arbitrary three-particle state can be perfectly teleported if the receiver introduces a collective unitary transformation. In this scheme, the unitary transformation is given uniquely, which is not the same as others. Finally, a guantum logical circuit which can carry out the unitary transformation is given.
