摘    要:We propose a simple method to generate a practical SU(2)-Schroedinger-cat state of a single trapped-ion vibration mode and the light field state, using the method based on a quantum system, which is composed of the onedimensional trapped-ion motion and a single cavity field mode. Moreover, the method proposed can be used for the generation two-mode maximal quantum entangled state. The detection of such a state is also briefly discussed.

关 键 词:量子电动力学  离子俘获腔  色散相互作用  非经典双模态  振动模式  光场态
