Studies of Two-Level Atoms in Driven Optical Cavities

在本项目中，研究人员将利用新开发的波粒相关器实验研究制备的量子态的动态演化。在腔QED系统中，光泵浦原子与驱动的高精细度光腔的单模相互作用，波粒相关器测量的条件场将允许重建量子态的演化。条件测量将与量子反馈控制相结合，以找到稳定量子态的方法。还将通过观察相关和测量反作用之间的关系，对相关函数中时间不对称性的发展进行新的研究。

In this project the investigators will study experimentally the dynamic evolution of prepared quantum states using a newly-developed wave-particle correlator. In a cavity QED system, where optically pumped atoms interact with a single mode of a driven high finesse optical cavity, the conditional field measured by the wave-particle correlator will allow the reconstruction of the evolution of the quantum state. The conditional measurements will be coupled to quantum feedback control to find ways to stabilize the quantum state. A new study of the development of time asymmetries in correlation functions by looking at the relationship between correlations and measurement back action will also be undertaken.
