We find the noise sensitivities (i.e., the quadratic terms of the energy with respect to the perturbation of the noise) of a particle shuttled by an optical lattice that moves according to a shortcut-to-adiabaticity transport protocol. Noises affecting different optical lattice parameters, trap depth, position, and lattice periodicity, are considered. We find generic expressions of the sensitivities for arbitrary noise spectra but focus on the white-noise limit as a basic reference, and on Ornstein-Uhlenbeck noise to account for the effect of non-zero correlation times.
我们研究了一个由光学晶格穿梭的粒子的噪声敏感性（即能量相对于噪声扰动的二次项），该光学晶格根据绝热捷径传输协议移动。我们考虑了影响不同光学晶格参数（阱深、位置和晶格周期性）的噪声。我们找到了任意噪声谱敏感性的一般表达式，但将重点放在白噪声极限作为基本参考，并考虑奥恩斯坦-乌伦贝克噪声以解释非零相关时间的影响。
