Reaching the Intrinsic Noise of an Absolute Quantum Gravimeter

This is the authors' abstract. We don't add key points for this paper.

Over the past decades, gravimeters with different working principles have been developed, such as superconducting gravimeters, spring gravimeters or gravimeters based on optical interferometry [1]. Their ability to measure local changes in gravitational acceleration with very high sensitivity makes these instruments widely used in fundamental physics, geodesy and geophysics [2]–[4]. Recently, quantum gravimeters based on matter wave inter-ferometry have demonstrated some of the best resolutions and stabilities [5].
