论文摘要
我们通过两个不同的一维开放QED晶格研究了光学非线性在光传播中的作用，即一系列Qubits链，在最近的邻居和一个连接的谐振器之间直接耦合到与每个量子的连接的谐振器链链链，将量子耦合到侧耦合。使用更准确的截短的海森堡 - 兰格方程方法，我们显示了由于有效的光子 - 光子相互作用和由速度非线性介导的相关光子阻滞而导致这些晶格的强度降低，而在这些晶格中的强度增加。与直接耦合量子位相比，由于光子饱和，我们发现侧耦合量子位的光透射量的复兴相对较高。我们发现，在没有大量耗散的情况下，标准的准经典分析无法捕获由于有效的光子 - 光子相互作用而导致的光透射率的减少。然后，我们设计了一种系统性方法来修改准经典分析以给出更好的结果。
We investigate the role of optical nonlinearity in light propagation through two different one-dimensional open QED lattices, namely a chain of qubits with direct coupling between the nearest neighbors and a chain of connected resonators to each of which a qubit is side-coupled. Using the more accurate truncated Heisenberg-Langevin equations method we show a reduction of light transmission with increasing intensity in these lattices due to effective photon-photon interactions and related photon blockade mediated by nonlinearity in qubits. In contrast to the direct-coupled qubits, we find a revival in the light transmission in the side-coupled qubits at relatively higher intensities due to saturation of qubits by photons. We find that in absence of bulk dissipation the standard quasi-classical analysis fails to capture the reduction in light transmission due to effective photon-photon interaction. We then devise a systemic method to modify the quasi-classical analysis to give much better results.
