英文摘要: The quantum optical information processing based on nanophotonics has great potential in the the development of high-speed information processing. However, achieving high-efficiency, small-scale, controllable integrated quantum photosource and optical quantum information processing devices is stil one of the key challenges should to be solved. According to above application requirements and key issues, this project will investigate the interaction between semiconductor quantum dots and metallic nanostructure surface plasma. Based on electrodynamics and quantum theory,using the theoretical modeling, numerical simulation, parameter optimization and experimental validation, this project will deeply study the binding energy and dynamic characteristics of exciton and biexciton in semiconductor quantum dots. The physical mechanisms and key parameters of the coupling interaction between complex excition and plasmon will also be analysed. Through the preparation of semiconductor epitaxial quantum dots and optimizing design of metal micro-nano structures, the excitation, coupling and control issues of quasi-particle like surface plasmon and excition in nanophtonics will be solved, which provides theoretical guidance and technical support for the design and development of key components for quantum optical information pr
