摘　　要：为实现简单经济的量子隐形传态,提出利用5粒子团簇态实现3粒子GHZ态的隐形传态方案.团簇态具有持续纠缠性和最大连通性等特点,很适合作为量子信道,可实现绝对安全的信息传递.该方案需要发送者进行两次Bell基联合测量、一次Hadamard变换和一次单粒子测量,并将测量结果通过经典信道告诉接收者.接收者根据发送者的测量结果,进行一次控制非门操作和相应的幺正变换,就可以实现量子的隐形传态,传输成功概率为100%.该方案中的操作比较简单,在实验上比较容易实现,具有很强的可操作性.To achieve a simple and economical quantum teleportation, a teleportation scheme of thethree-particle GHZ state by using the five-particle cluster state is proposed in this paper. As the cluster state ischaracterized by the persistent entanglement and maximal connectivity, it is proper for being a quantum channel,which can realize the information transmission with absolute security. This scheme requires the sender to carry outtwo Bell-based joint measurement, a Hadamard transform and a single particle measurement, and the recipient istold the measurement results over the classical channel. By the measurement results sent, the recipient carries outa CNOT operation and corresponding unitary transformation, and realizes the quantum teleportation, whosesuccessful probability is 100%. And this scheme is of simple operation, easy experimentally implementation, anda strong operability.
