| 摘 要： | 研究了用4个粒子的非最大纠缠纯态传输二能级二粒子的一般态。传输方案没有利用Bell基测量，而是利用么正变换和局域进行了测量。在经典通讯的帮助下，通过做适当的么正变换和对辅助量子位的测量，这个二粒子一般态可以一定的成功几率从发送者处传输到接收者处。

| Abstract: | A scheme for probabilistic teleporting unknown quantum pure state of two 2-level particles state of general formation by partly pure entangled four-particle states is proposed. Unitary transformation and local measurement take the place of Bell operator measurement, then proper unitary transformation and the measurement on an auxiliary qubit with the aid of classical communication are performed. In this way the unknown quantum state of two-particle state of general formation can be reconstructed at another place with certain probability. |
