| 摘 要： | 提出利用四粒子团簇态传送一个未知两粒子纠缠态从而实现可控量子隐形传态的方案,发送者对她自己拥有的3个粒子做一次三粒子纠缠完备基联合测量,控制者对其拥有的粒子作局域测量,接收者在控制者的帮助下对其自己拥有的两粒子做相应的幺正变换,即可重新构造出发送者要传送的未知态,完成了可控量子隐形传态.

| Abstract: | A general scheme for controlled teleportation of an unknown two-qubit entangled state with four-qubit cluster state is proposed.The sender performs a measurement by three particles entangled basis on her own three qubits and the controller needs also take a local measurement.The receiver can reconstruct the unknown state teleported by the sender by performing appropriate unitary operations on his particles if he cooperates with the controller,then the controlled teleportation is accomplished. |

| Keywords: | quantum information controlled quantum teleportation a complete set of three particles entangled states cluster state the most entangled state |
