英文摘要： Optomechanical system, optical field interacting with mechanical oscillator, is not only involving the basic problems of quantum mechanics but also can be used as important quantum devices such as quantum sensors, information controller, gate operation ect.. Therefore, the optomechanical system plays significant role in quantum mechanics as well as in quantum information domain and has attracted a lot of attention. In this project, we will research the hybrid cavity optomechanical system. Intend to find effective scheme to realizing the quantum steady-pure state of macro (mesoscopic) oscillators. We aim to propose a completely theoretical method to deal with nonlinear problems in strong coupling region and try to find a feasible scheme to effectively enhance the nonlinear coupling. Explore the quantum information control by manipulating the atoms. We plan to study the synchronization, the relation between synchronization and entanglement. We will put forward a method to judge or measure the synchronization. We are going to investigate the transmission of quantum information, quantum gate operation, ect.. Through the implementation of this project, a more comprehensive and systematic study of the cavity optomechanical system will be accomplished, which will not only enrich the theoretical knowledge of the hybrid system but also provide guidance for the application of the quantum devices.
