系统地研究了两个量子化光场与一个由经典光场驱动的循环原子系综的相互作用。这种所谓的原子循环系综由三能级原子组成，由于对称性破缺而具有Delta型跃迁，这也可以在超导量子电路中实现。95，087001（2005）]。我们探讨了通过对原子-光子系统的相干操纵，在光子态之间以及光子与原子集体激发之间产生量子纠缠的动力学机制。结果表明，量子信息可以从一个量子化光模完全转移到另一个量子化光模，通过对经典光场拉比频率的控制，两个量子化光场携带的量子信息可以存储在原子系综的集体模中.
We systematically study the interaction between two quantized optical fields and a cyclic atomic ensemble driven by a classic optical field. This so-called atomic cyclic ensemble consists of three-level atoms with Delta-type transitions due to the symmetry breaking, which can also be implemented in the superconducting quantum circuit by Yu-xi Liu et al. [Phys. Rev. Lett. 95, 087001 (2005)]. We explore the dynamic mechanisms to creating the quantum entanglements among photon states, and between photons and atomic collective excitations by the coherent manipulation of the atom-photon system. It is shown that the quantum information can be completely transferred from one quantized optical mode to another, and the quantum information carried by the two quantized optical fields can be stored in the collective modes of this atomic ensemble by adiabatically controlling the classic field Rabi frequencies.
