论文摘要
我们研究了一个单个光子在任意叠加状态下沿波导传播的单个光子的散射,两个频率在两个非降级基态的叠加中具有单个三级$λ$原子,在该叠加中,原子耦合到波导。我们发现散射取决于光子频率之间的相对相和原子接地态之间的相对相。我们的结果表明,耦合到波导的三级$λ$原子可以用作光子相滤波器,可以检测光子叠加态的两个频率之间的相对相。
We study the scattering of a single photon propagating along a waveguide in an arbitrary superposition state two frequencies with a single three-level $Λ$ atom in a superposition of two non-degenerate ground states where the atom is coupled to a waveguide. We find that the scattering depends on both the relative phase between the photon frequencies and the relative phase between the atomic ground states. Our results show that a three-level $Λ$ atom coupled to a waveguide can be used as photon phase filter that could detect the relative phase between the two frequencies of the photon superposition state.
