CAREER: Continuous Measurements of Quantum Dynamical Systems

这个职业项目的重点是更好地理解超冷原子运动的连续量子测量。这项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。这一研究方向从一个相对简单的实验开始，研究两个原子的共振荧光中的测量诱导干涉。散射光中干涉图案的出现是相对位置量子测量的标志，这是一种与原子运动的色散趋势相反的动态崩塌过程。下一个目标是通过成像探测激光散射的光来演示单个原子的时间和空间分辨率测量--这是连续海森堡显微镜的实现。这将允许对连续测量过程进行彻底的表征，包括对测量记录中量子关联的出现和经典轨道行为的研究。这项研究计划的一个长期目标是研究单个量子系统的反馈控制。教育部分包括与高中教师的接触，以及针对非理科专业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.
