Welcome to visit the homepage of cavity quantum electrodynamics (CQED) research group in the State Key Laboratory of Quantum Optics and Quantum Optics Devices and the Institute of Opto-Electronics, Shanxi University! We are exploring the interaction between light and matter in a strongly confined space, i.e. the cavity quantum electrodynamics. The study mainly focuses on the system of strongly coupled cesium atoms and optical cavity, and the fundamental problems and new technologies about quantum information processing, quantum resources, quantum metrology are currently under investigation. The researches of manipulation of single atoms, fabrication of nano optical fiber, and the quantum enhanced quantum measurement are also being performed. For more details, click here. You are welcome to visit or join us!
