Atom interferometry provides the opportunity of high-precision measurements of rotation and acceleration [1]. Therefore atoms are the ultimate quantum sensors. In the configuration of an atom interferometer they provide the opportunity of high-precision rotation and acceleration sensing. Potential applications range from the further understanding of fundamental physics to inertial navigation and geological exploration. In the QUANTUS freefall experiments atom interferometery is the central method as well [2].Atom interferometry provides the opportunity of high-precision measurements of rotation and acceleration [1].

We show that light-pulse atom interferometry with atomic point sources and spatially resolved detection enables multiaxis (two rotation, one acceleration) precision inertial sensing at long interrogation times. Using this method, we demonstrate a light-pulse atom interferometer for $^{87}\mathrm{Rb}$ with 1.4 cm peak wave packet separation and a duration of $2T=2.3\text{ }\text{ }\mathrm{s}$ . The inferred acceleration sensitivity of each shot is $6.7\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}12}g$, which improves on previous limits by more than 2 orders of magnitude. We also measure Earth's rotation rate with a precision of $200\text{ }\text{ }\mathrm{nrad}/\mathrm{s}$ .We show that light-pulse atom interferometry with atomic point sources and spatially resolved detection enables multiaxis (two rotation, one acceleration) precision inertial sensing at long interrogation times.
