论文摘要
绝热性（STA）的快捷方式已在理论上和实验上成功地应用于各种量子控制任务。在先前的工作中，作者已经开发了针对绝热性快捷方式的分析扩展，称为“增强的绝热”（ESTA），将STA方法扩展到无法直接应用STA的系统[phys。 Rev. Research 2，023360（2020）]。在这里，我们概括了这种方法，并构建一种利用高阶项的替代ESTA方法。我们将这种ESTA方法应用于高斯陷阱和手风琴晶格电位的扩展，这表明ESTA的保真度和鲁棒性提高了。
Shortcuts to adiabaticity (STA) have been successfully applied both theoretically and experimentally to a wide variety of quantum control tasks. In previous work the authors have developed an analytic extension to shortcuts to adiabaticity, called enhanced shortcuts to adiabaticity (eSTA), that extends STA methods to systems where STA cannot be applied directly [Phys. Rev. Research 2, 023360 (2020)]. Here we generalize this approach and construct an alternative eSTA method that takes advantage of higher order terms. We apply this eSTA method to the expansion of both a Gaussian trap and accordion lattice potential, demonstrating the improved fidelity and robustness of eSTA.
