| 摘 要： | 提出利用2个二粒子部分纠缠态作为量子信道,实现四粒子纠缠W态的概率隐形传输方案.发送者做3次幺正变换和2次Bell基测量,然后接收者通过引入辅助粒子并做适当的幺正变换,就能以一定的概率完成四粒子纠缠W态的隐形传输.

| Abstract: | A scheme for probabilistic teleportation of a four-particle entangled W state is given. Two partially entangled two-particle states are used as the quantum channel. A four-particle entangled W state can be perfectly teleported probabilistically from the sender to the receiver if the sender performs three unitary transformations and two Bell-state measurements while the receiver introduces auxiliary particles and performing appropriate unitary transformations. |
