我们提出了一个非最大纠缠EPR对和一个GHZ态作量子通道实现一个任意两粒子量子态隐形传递的方案.利用Bell态测量和Hadamard门测量,如果接收者引入一个联合幺正变换,就能实现一个任意两粒子态的概率传递,这个联合幺正变换是唯一的.同时,我们还给出了实现该传态过程的量子电路.
我們提齣瞭一箇非最大糾纏EPR對和一箇GHZ態作量子通道實現一箇任意兩粒子量子態隱形傳遞的方案.利用Bell態測量和Hadamard門測量,如果接收者引入一箇聯閤幺正變換,就能實現一箇任意兩粒子態的概率傳遞,這箇聯閤幺正變換是唯一的.同時,我們還給齣瞭實現該傳態過程的量子電路.

We present a scheme to probabilistically teleport an arbitrary and unknown two-particle state via a nonmaximally entangled EPR pair and a non-maximally entangled GHZ state as the quantum channel. With the help of Bell-state measurements and Hadarmard measurement, an arbitrary two-particle state can be perfectly teleported if a receiver introduces a collective unitary transformation. The unitary transformation is given uniquely. Also, we present a quantum circuit for realizing the teleportation successfully.
