研究无Bell基测量的未知两粒子纠缠态的隐形传态方案。Alice需传送未知两原子纠缠态给Bob，以她和Bob的原子组成的最大纠缠GHZ态作为量子信道，通过两原子同时在一个强经典驱动场驱动下和一个单模腔场发生相互作用，产生态的演化，从而实现隐形传态。本方案可忽略腔场热作用和腔延迟作用的影响，传送成功的总几率为1。

We propose a scheme for the teleportation of an unknown two-particle entangled EPR state without the Bellstate measurement. Alice needs to teleport an unknown two-particle EPR state to Bob. Her atoms and Bob's are prepared in the maximal entangled GHZ state,which forms the quantum channel. She sends two atoms through a single-mode cavity field,and drives them by a strong classical field at the same time. Through the interaction between the atoms and the cavity,the states of these atoms are evolved. After the interaction,Alice realizes the teleportation successfully. In the scheme,the effects of thermal field and cavity decay are all eliminated. The success probability is 1.0,and the fidelity is 1.0 too.
