摘　　要：提出用1个任意三粒子W态作为量子信道实现双粒子的受控传递,可以将未知量子态传送给2个接收者中的任意1个.用腔量子电动力学技术,对非最大纠缠态进行提纯,实现未知量子态的概率传送.通过腔与原子共振相互作用实现未知量子态的概率传送而非机械的进行幺正变换,有较大的可行性.A scheme for an arbitrary three-particle non-maximally entanglement W state as quantum channel is to achieve the controlled teleporting of two-particle, teleporting unknown quantum state form a sender to either of the two receivers. By the technology of cavity quantum eleetrodynamies, purifying the non-maximally entanglement state on cavity quantum eleetrodynamics is purified, the teleportation probability is realized. Transfer with the atoms through the catity resonance interaction to achieve the probability of an unknown quantum state transfer, machinery rather than the conduct of unitary transformation, has greater the feasibility.
