论文摘要
我们提出了一种通过使用腔体辅助拉曼过程以及腔光子光子介导的相互作用来同时激发两个原子的方法。该系统由一个两级原子和$λ$ -Type或V型三级原子组成，它们与空腔模式耦合在一起。衍生出有效的哈密顿量后，我们发现在某些情况下，单个光子可以同时激发两个原子。另外，多个光子甚至经典场也可以同时激发两个原子。例如，我们展示了一种方案，可以在电路QED设置中实现我们的建议，该设置是人造原子与空腔相结合的。通过实验可行的参数研究了该过程的动力学和量子统计特性。
We propose an approach to simultaneously excite two atoms by using cavity-assisted Raman process in combination with cavity photon-mediated interaction. The system consists of a two-level atom and a $Λ$-type or V-type three-level atom, which are coupled together with a cavity mode. Having derived the effective Hamiltonian, we find that under certain circumstances a single photon can simultaneously excite two atoms. In addition, multiple photons and even a classical field can also simultaneously excite two atoms. As an example, we show a scheme to realize our proposal in a circuit QED setup, which is artificial atoms coupled with a cavity. The dynamics and the quantum statistical properties of the process are investigated with experimentally feasible parameters.
