Abstract

In analogy to light interferometers, atom interferometers are sensitive to rotations if they enclose an area. Due to the different energy scales of the interfering particles, atom interferometers can potentially reach competitive sensitivities to large laser gyroscopes while maintaining a comparably compact and transportable sensor size [1]. In this contribution, we will introduce the principle of atom interferometry, discuss the current status of rotation sensors based on atoms in free fall as well as relevant developments, and show a concept for a multi-loop atomic Sagnac interferometer with an anticipated sensitivity of 20 prad/s at 1 s [1].
