Abstract

Quantum sensors based on light pulse atom interferometers allow for 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 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.

量子气体的惯性传感：用于原子干涉测量的冷凝源与热源的比较性能研究

摘要

基于光脉冲原子干涉仪的量子传感器可以测量惯性力和电磁力，例如精确确定基本常数（作为精细结构常数）或测试现代物理学的基本定律（作为等效原理）。当可以执行较大的询问时间和/或较大的动量传递时，这些方案将充分发挥其性能。在本文中，我们演示了当挑战现有技术时，如何使用Bose-Einstein压缩源可以使干涉测量受益。在三种基于地球和空间的传感器的科学案例中，我们将Bose-Einstein冷凝源与热源引起的系统和统计效果进行了对比。
