论文摘要
基于光脉冲原子干涉仪的量子传感器允许对惯性和电磁力进行高精度测量，例如将基本常数准确地确定为良好的结构常数或测试现代物理的基础定律作为等效原理。当可以实施大量审问时间和/或大型动量转移时，这些方案将展现出其全部性能。在本文中，我们证明了当挑战最新情况时，精度干涉法可以从使用Bose-Einstein凝结来源中受益。在三个示例性的地球和空间传感器的科学案例中，我们将Bose-Einstein凝结的源与热源相比对比，并将其与热源进行了对比。
Quantum sensors based on light-pulse atom interferometers allow for high-precision measurements of inertial and electromagnetic forces such as the accurate determination of fundamental constants as the fine structure constant or testing foundational laws of modern physics as the equivalence principle. These schemes unfold their full performance when large interrogation times and/or large momentum transfer can be implemented. In this article, we demonstrate how precision interferometry can benefit from the use of Bose-Einstein condensed sources when the state of the art is challenged. We contrast systematic and statistical effects induced by Bose-Einstein condensed sources with thermal sources in three exemplary science cases of Earth- and space-based sensors.
