摘要
提出利用6粒子团簇态传送1个未知单粒子态从而实现可控量子隐形传态的方案,发送者对自己拥有的粒子做1次5粒子von-Neumann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,该方案成功的概率为100%.
A new scheme for controlled teleportation of an arbitrary single-qubit state is proposed in detail,using a six-qubit cluster state as quantum channel.For an arbitrary single-qubit state,the sender performs a joint von Neumann measurement on the five qubits of his own,and the controller performs a single-qubit projective measurement,then the receiver can reconstruct the arbitrary single-qubit state by performing some appropriately unitary transformations on his qubit after he knows the measurement results of both the sender and the controller.The probability of the success of the program is 100%.
