CAREER: Continuous Measurements of Quantum Dynamical Systems

这个CAREER项目的重点是更好地理解超冷原子运动的连续量子测量。该研究将通过原子与经典激光场相互作用的自由空间动力学实验，详细描述连续量子测量的特征。本研究方向从一个相对简单的实验开始，研究两个原子共振荧光中的测量诱导干涉。在散射光中出现干涉图案是相对位置的量子测量的特征，这是一个与原子运动的色散趋势相对抗的动态坍缩过程。下一个目标是演示一个时间和空间分辨测量单个原子通过成像光从探针激光散射-实现连续海森堡显微镜。这将允许对连续测量过程进行彻底的表征，包括研究测量记录中量子相关性和经典轨迹行为的出现。本研究计划的长期目标是研究单量子系统的反馈控制。教育部分包括与高中教师的接触，以及针对非科学专业学生的疯狂科学家课程的开发。

This CAREER project focuses on achieving a better understanding of continuous quantum measurements of the motion of ultracold atoms. The research will characterize continuous quantum measurements in detail through experiments on the free-space dynamics of atoms interacting with classical laser fields. This research direction begins with a relatively simple experiment to study measurement-induced interference in the resonance fluorescence of two atoms. The emergence of an interference pattern in the scattered light is the signature of a quantum measurement of relative position, a dynamical collapse process that counters the dispersive tendencies of the atomic motion. The next goal is to demonstrate a time- and space-resolved measurement of a single atom by imaging light scattered from a probe laser - a realization of a continuous Heisenberg microscope. This will allow a thorough characterization of a continuous measurement process, including studies of the emergence of quantum correlations and classical-like trajectory behavior in the measurement record. A long-term goal of this research plan is to study the feedback control of a single quantum system. The educational component involves outreach to high school teachers and the development of a mad scientist course aimed at non-science majors.
