【摘要】 提出用一个任意三粒子非最大纠缠W态作为量子信道,将未知量子态传送给两个接收者中的任意一个,用腔量子电动力学技术Cavity-QED(Cavity quantum electrodynamics)对非最大纠缠态进行提纯,实现未知量子态的概率传送.分析了作为量子信道的纠缠态系数对于成功实现隐形传送的影响,并以原子与腔共振相互作用演化来代替复杂的幺正变换,让接收方通过经典信息重新构造出初始传送态,成功的几率取决于3个系数中2个比较小的系数.以现在的技术是可以实现的.更多还原

【Abstract】 In the letter,a scheme for an arbitrary three-particle non-maximally entanglement W state as quantum channel,teleporting unknown quantum state form a sender to either of the two receivers,and purifying the non-maximally entanglement state on cavity QED,realize the teleportation probability. And analyses the successful teleport atomic state which affected by coefficient of the quantum channel,atomic state resonant interaction with cavity state instead of complex Unitary Transformation. The probability of successful teleportation is determined by two smaller coefficients of the entangled. this scheme can be realized by current technologies.更多还原
