本文演示了如何利用量子最优控制来实现抖动晶格干涉测量。第一个目标是将干涉测量的五个基本阶段(分裂、传播、反射、反向传播和复合)转化为由每个阶段的时间视界参数化的量子最优控制问题。然后研究每一级的时序与其对干涉仪性能的总体影响的关系。这是通过比较在不同加速度范围内获得的总体分布，并使用Fisher信息来估计所得到的加速度计的灵敏度来实现的。这些令人鼓舞的结果突显了量子最优控制在下一代原子干涉仪设计中的有效性。
This paper demonstrates how quantum optimal control can be used to perform shaken lattice interferometry. The first objective is to translate the five fundamental stages of interferometry (splitting, propagation, reflection, counter propagation and recombination) into quantum optimal control problems parametrized by the time horizon of each stage. The timing of each stage is then studied in relationship to its overall influence on the interferometer performance. This is done by comparing the population distributions obtained for a range of different accelerations and using Fisher information to estimate the sensitivity of the resulting accelerometer. These encouraging results highlight the effectiveness of quantum optimal control for the the design of next-generation atom-based interferometers.
