| 摘 要： | 研究了用六粒子的非最大纠缠纯态传输二能级三粒子的一般态.传输方案没有利用Bell基测量,而是利用幺正变换和局域进行了测量.在经典通讯的帮助下,通过做适当的幺正变换和对辅助量子位的测量,这个三粒子一般态可以一定的成功概率从发送者处传输到接收者处. |

| Abstract: | A scheme for probabilistic teleporting unknown quantum pure state of three 2-level particle state of general formation by partly pure entangled six-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. |
| Keywords: | probabilistic teleportation entangled state three-particle state of general formation discrete Fourier transform controlled-not gate local measurement |
