Abstract
Abstract The sensing of gravity has emerged as a tool in geophysics applications such as engineering and climate research 1–3 , including the monitoring of temporal variations in aquifers 4 and geodesy 5 . However, it is impractical to use gravity cartography to resolve metre-scale underground features because of the long measurement times needed for the removal of vibrational noise 6 . Here we overcome this limitation by realizing a practical quantum gravity gradient sensor. Our design suppresses the effects of micro-seismic and laser noise, thermal and magnetic field variations, and instrument tilt. The instrument achieves a statistical uncertainty of 20 E (1 E = 10 −9 s −2 ) and is used to perform a…
