摘要:
提出了一个能实现3粒子GHZ态1→2的量子远程克隆方案:运用2个4粒子纠缠态作为量子信道,通过发送者的2次Bell测量、Hadamard变换、单粒子测量及经典通信;2个接收者进行相应的幺正变换、引入附加粒子和通过Toffoli门,就可以得到原未知态的近似拷贝,此方案的保真度与输入态有关.另外,还推广了一种实现N粒子GHZ态1→2的量子远程克隆方案.
Abstract:
A scheme for 1→2 quantum telecloning of a three-particle GHZ state using two four-particle entangled state as the quantum channel.After the sender's two Bell measurements,Hadamard transformation,single particle measurement and classical communication,the two receiver perform proper unitary operation and introduce auxiliary particles,then let their particles through a Toffoli gate respectively,the receivers can get the approximate copy of the original unknown state.The fidelity of this scheme is related to the input state.In addition,we generalized the 1→2 quantum telecloning scheme of three-particle GHZ state to the situation of rticle GHZ state.
