摘　　要：提出了一种无Bell基测量一对多隐形传输二比特信息的方案.在隐形传输过程中,以(2n+2)个粒子的最大纠缠态作为量子信道,通过原子在外加强经典驱动场下和单模腔场的相互作用,产生态的演化,从而实现隐形传输.传输过程中不需要用到Bell基测量,且不用考虑腔场耗散和外界热场环境的影响,传输成功的总几率为1.0.Quantum teleportation of two qubits based on One-to-Many without the Bell-state measurement is proposed. In the scheme of teleportation, （2n ＋ 2）-particle entanglement is required as the quantum channel. The teleportation can be realized by sending atoms into a single-mode cavity which is driven by a strong classical field at the same time. During the interaction of the atoms with the cavity, the states of these atoms evolve. The scheme immunes the effects of thermal field and cavity decay. The success probability is 1.0.
