任意三粒子态的概率隐形传输

Probabilistic Teleportation of an Arbitrary Three-particle State

给出了1个任意三粒子态的概率隐形传输方案.信道由1个二粒子部分纠缠态,1个三粒子部分纠缠GHZ态和1个三粒子部分纠缠W态组成.发送者作3次Bell基测量,然后接收者在第3方的帮助下(执行Hadamard操作和简单测量)引入合适的么正变换,就可以使1个任意三粒子态以确定的概率成功地由发送者传给接收者.成功的概率是由3个部分纠缠态的最小的系数决定的.

A scheme for probabilistic teleportation of an arbitrary and unknown three-particle state is given.A partially entangled two-particle state,a partially entangled three-particle GHZ state and a partially entangled three-particle W state are used as the quantum channel.An arbitrary and unknown three-particle state can be perfectly teleported probabilistically from the sender to the receiver if the sender performs three Bell-state measurements while the receiver introduces an appropriate unitary transformation with the help of the third man(the Hadamard operation and simple measurements).
