中文摘要：

为实现量子隐形传态,利用量子纠缠现象,提出基于四粒子团簇态传送一个未知的二粒子任意态的方案。方案中,发送者和接收者共享一个四粒子团簇态,发送者首先对要传送给接收者的未知二粒子态与四粒子中的粒子2和粒子4做一次四粒子von-Neumann联合测量,并且通过经典信道将其测量的结果告诉接收者。接收者根据从经典信道收到的测量结果,做相对应的幺正变换。在整个通信过程中,发送者没有将原有粒子发送给接收者,但是接收者已经重构出发送者手中原始的二粒子态,实现了量子隐形传输,完成了通信双方的通信。

英文摘要：

In order to complete the quantum teleportation, we propose a quantum teleportation scheme of arbitrary two-qubit cluster state by using a four-qubit cluster state based on quantum entanglementphenomenon in this paper. In this scheme, the sender and the receiver share a four-qubit cluster state. The sender first performs a joint von- Neumann measurement on the qubits in his hand. And he sends the measurement results to the receiver through the classical channel. The receiver performs corresponding unitary operation according to the measurement results he re- ceived. In the process of this communication, the sender does not tell the original arbitrary two-qubit cluster state to the receiver, but he reconstructs the arbitrary two-qubit state. The quantum teleportation comes true through these processes and the mutual communication is completed.
