This experimental research program focuses on the development of methods for learning control to yield information about the forces controlling quantum dynamics. This quantum control will use optical tools such as mode-locking, Fourier filtering, and parametric conversion to tailor fields to turn on and off in femtoseconds or less, and change their characteristics faster than a chemical bond can open or an atom can ionize. Unlike tunable laser absorption, laser cooling, or optical pumping, all of which also can control quantum states, strong field control can induce interactions so rapidly that decoherence from the environment or the electromagnetic vacuum cannot interfere. The broader impact of the program involves student education and outreach to the community.

该实验研究计划的重点是开发学习控制方法，以产生有关控制量子动态的力的信息。该量子控制将使用光学工具，例如模式锁定，傅立叶过滤和参数转换，以量身定制磁场以在femtsecond或更少的情况下打开和关闭，并比化学键可以打开或原子更快地更改其特性。与可调的激光吸收，激光冷却或光泵（所有这些都可以控制量子状态）不同，强场控制可以迅速诱导相互作用，以至于从环境或电磁真空吸尘器上的反应性不会造成干扰。该计划的更广泛影响涉及学生教育和向社区推广。
