摘　　要：提出用原子与腔场的纠缠态作为量子信道,并利用腔量子电动力学技术实现弱相干态的隐形传送,退相干现象会在很大程度上避免,实现了非贝尔态测量,分析了平均光子数对传送相干态的影响,也反映了相干态的非正交特性.A scheme for teleportation of weak entangled coherent state is proposed by using the cavity quantum electrodynamics （QED）. We prepare an cavity entangled with an atom as the quantum channel. In this letter decoherent phenomena can be avoided in very degree, we also realize the probability of successful teleportation via no - Bell Measurement detection. It found that the non -orthogonal properties of the entangled coherent states is reflected, and analyzes the success of teleportation affected by the mean photons in this letter.
