摘要
给出了利用两个二能级原子和耦合腔双光子过程相互作用系统实现量子信息转移的方案。该方案中二能级原子通过双光子跃迁与单模腔场发生共振相互作用。通过控制原子与光场的相互作用时间,实现量子信息从一个原子转移到另一个原子。
A scheme is proposed for transferring quantum information with the system of atoms interacting with coupled cavities.The scheme is based on the resonant interaction of two-level atom with cavity field via a two-photon hopping.Through controlling the time of atom interacting with the cavity field,the quantum information can be transferred from an atom to another atom or from a cavity to another cavity.
