We have theoretically studied schemes improving efficiencies of nonlinear responses between photons and organic molecules (quantum dots). We focus on the system where the molecules are coupled with auxiliary systems, e.g., optical antenna using a small piece of metal nanometers and cavity mode in the semiconductor microstructure. As a result, we developed a method to create an entangled state between quantum dots in distant cavities. Besides, considering coupled systems that consists of optical antenna and molecules (quantum dots), we revealed the conditions to enhance nonlinear optical excitations. All of the results can be explained by considering quantum interferences between composition elements of the entire systems. In addition, by combining quantum master equation and the discrete dipole approximation method, a scheme to calculate the nonlinear response on the assumption that specific system was developed.

我们从理论上研究了提高光子和有机分子（量子点）之间非线性响应效率的方案。我们专注于分子与辅助系统耦合的系统，例如，光学天线采用一小片金属纳米和腔模的半导体微结构。 因此，我们开发了一种方法，在遥远的腔中的量子点之间创建纠缠态。此外，考虑光学天线和分子（量子点）的耦合系统，我们揭示了增强非线性光学激发的条件。所有的结果都可以通过考虑整个系统组成元素之间的量子干涉来解释。此外，结合量子主方程和离散偶极子近似方法，提出了一种在特定系统假设下计算非线性响应的方法。
