摘要
利用Λ型三能级原子与相干态光场的Raman相互作用,制备出原子与腔场的四粒子纠缠态,用该纠缠态作为量子信道,把量子信道中的一个粒子作为控制粒子,我们可以实现对未知的两粒子纠缠态的量子受控传递.基于目前的腔量子电动力学的实验技术,简单讨论了我们方案的实验可行性.
A four-particle entangled state of atoms and cavity is prepared through the Raman interaction of ∧- type three-level atom with coherent cavity-field. The four-particle entangled state is used as the quantum channels,and one of the particles in the channel is used as the controlled qubit. We can realize the controlled teleportation of an unknown two-particle entangled state. Based on present cavity QED techniques,We give a brief discussion on the experimental feasibility.
