英文摘要: Solid-state quantum systems, owing to their integratability, controllability, scalability, low energy consumption,have attractive applications. To study coherent control of strong interaction between light and matter at single-photon level in solid-state quantum system, has important significance in optical quantum computation and quantum information processing. In our project, we will investigate coherent controlling single-photon transport and generating optical nonlinearity at single-photon level, utilizing strong light-matter interaction in solid-state quantum system. These solid-state systems mainly include circuit quantum electrodynamics system, strong-coupling waveguide-atom system and new-generation solid-state optomechanical system. We will concentrate on improving efficiency of existing scheme and developing new theoretical method under single-photon strong coupling regime using highly tunability and controllability of solid-state system. To study these problems has important significance in improving our understanding on light-matter interaction, developing solid-state single-photon quantum device, and optimizing existing scheme of quantum information processing and storage.
