Entanglement-Enhanced Atomic Gravimeter by Christophe Cassens, Bernd Meyer-Hoppe, Ernst Rasel, Carsten Klempt

“…Here, we present a gravimeter based on Bose-Einstein condensates with a sensitivity of -1.7_{-0.5}^{+0.4}  dB beyond the standard quantum limit. Interferometry with Bose-Einstein condensates combined with delta-kick collimation minimizes atom loss in and improves scalability of the interferometer to very-long-baseline atom interferometers.…”
