提出了一种利用最大纠缠态EPR对和团簇态作为量子通道实现任意两粒子态受控隐形传态的方案。控制器接收到Alice的贝尔状态测量结果后，在非最大纠缠贝尔基下对他的粒子进行联合测量。接收方需要引入一个辅助量子位，并对其粒子进行一系列适当的幺正变换。原始状态可以以2cos2 θ的概率被成功传送。
A scheme for controlled teleportation of an arbitrary two-particle state using a maximally entangled EPR pair and a cluster state as the quantum channel is proposed. After receiving Alice's Bell state measurement results, the controller performs a joint measurement on his particles under a non-maximally entangled Bell-basis. The receiver needs to introduce an auxiliary qubit, and performs a series of appropriate unitary transformations on his particles. The original state can be teleported successfully with the probability 2 cos2 θ.
