利用受激拉曼跃迁制备原子－光子的杂化纠缠态

提出了一种利用玻色-爱因斯坦凝聚体中三能级原子与一束较弱的相干态探测光和一束较强的经典耦合光相互作用产生受激拉曼跃迁制备原子－光子杂化纠缠态的理论方案。研究了探测光场与原子间的相互作用强度、双光子失谐量和处在基态的原子间的相互作用强度对制备杂化纠缠态的影响。结果表明，通过增加探测光场与原子间的相互作用强度或减小双光子失谐量，能够更快地制备纠缠程度更高的原子－光子杂化纠缠态。

Generating hybrid entangled state of atom-photon with stimulated Raman transition

A theoretical scheme was presented for generating atom-photon hybrid entangled state with stimulated Raman transition of three-level atoms in Bose-Einstein condensate interacting with a weaker coherent probe light and a stronger classical coupling light. We investigate the influences by the interaction strength between probe laser field and the atoms, two-photon detuning and the interaction strength between the atoms in the ground state. It’s shown that the atom-photon hybrid entangled state with better entanglement can be rapidly generated by increasing the interaction strength between probe laser field and the atoms or decreasing two-photon detuning.
