New Directions in Quantum Control

这个实验研究计划的重点是学习控制方法的发展，以产生关于控制量子动力学的力的信息。这种量子控制将使用锁模、傅立叶滤波和参数转换等光学工具来定制场，使其在飞秒或更短的时间内打开和关闭，并以比化学键打开或原子电离更快的速度改变其特性。与可调谐激光吸收、激光冷却或光泵浦（所有这些都可以控制量子态）不同，强场控制可以如此迅速地诱导相互作用，以至于来自环境或电磁真空的退相干无法干扰。该计划的更广泛影响包括学生教育和社区推广。

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.
