摘　　要：在二能级单粒子未知量子态的超空间传送方案和有控制者参与的受控二能级单粒子量子态超空间传送方案的基础上,分析了一般情况和受控情况下二能级二粒子量子态的超空间传送,并给出了详细的计算结果.同时简要讨论了这2种情况下任意数目的二能级系统的任意未知量子态的超空间传输问题.Based on the standard teleportation scheme and the controlled teleportation scheme for an unknown quantum state of a single two-level particle, it was generalized the discussion to two-particle cases and performed a detailed calculation for the two particle problem. It was discussed briefly the problem of transportation of any unknown quantum state of arbitrary number of two-level particles also.
