摘　　要：通过两粒子纠缠态作为量子信道,实现了四粒子GHZ态隐形传送的方案。首先提出该量子信道处在最大纠缠态时的传送,其次对两粒子纠缠为非最大纠缠态时的传送情形进行研究。通过相关的测量与操作,并且引入相应的辅助粒子,可以成功地实现隐形传送。相比于以往的传送方案,本方案不仅节约了量子信道的纠缠资源,而且操作也相对简单。This study proposing a new idea for quantum teleportation of a four-particle GHZ state through a two-particle entangled quantum channel. First, we take the maximally entangled states as quantum channel, then, for the actual situation, the case of nonmaximally entangled states is considered. By measuring the operation related and introducing an ancillary qubit, we find teleportation of four-particle entangled GHZ state can be implemented with a certain probability. Comparing with the teleportation scheme in the past, this scheme can not only save quantum channel entangled resources, but also simplify the operation relatively.
