论文摘要
波导量子电动力学中的理论研究占单光子和两光子fock状态（光子数状态）的输入，但实验主要是使用微弱的相干光进行的。我们创建了一个理论工具箱，通过两级或三级发射极嵌入在带有Fock状态或相干状态输入的开放式波导中，以两级或三级发射极的形式比较和对比度线性和非线性光散射。我们确定规则以比较两种输入类型的介质的光传输特性，介质的Kerr和Cross-Kerr非线性。对不同类型的输入的Kerr和Cross-Kerr效应的广义描述，以比较这些模型中两个光子之间的Kerr和Cross-Kerr非线性。
While the theoretical studies in waveguide quantum electrodynamics predominate with single-photon and two-photon Fock state (photon number states) input, the experiments are primarily carried out using a faint coherent light. We create a theoretical toolbox to compare and contrast linear and nonlinear light scattering by a two-level or a three-level emitter embedded in an open waveguide carrying Fock state or coherent state inputs. We identify rules to compare light transport properties, the Kerr, and cross-Kerr nonlinearities of the medium for the two types of inputs. A generalized description of the Kerr and cross-Kerr effect for different types of inputs is formulated to compare the Kerr and cross-Kerr nonlinearity between two photons in these models.
