Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

Quantum entanglement has been generated and verified in cold-atom experiments and
used to make atom-interferometric measurements below the shot-noise limit. However …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

Abstract Bose-Einstein condensates (BECs) in free fall constitute a promising source for
space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display …

The research on cold-atom interferometers gathers a large community of about 50 groups
worldwide both in the academic and now in the industrial sectors. The interest in this sub …

Gravitational waves (GWs) were observed for the first time in 2015, one century after
Einstein predicted their existence. There is now growing interest to extend the detection …

Ultracold quantum gases are ideal sources for high-precision space-borne sensing as
proposed for Earth observation, relativistic geodesy and tests of fundamental physical laws …

Microgravity eases several constraints limiting experiments with ultracold and condensed
atoms on ground. It enables extended times of flight without suspension and eliminates the …

Recent developments in quantum technology have resulted in a new generation of sensors
for measuring inertial quantities, such as acceleration and rotation. These sensors can …

We report an airborne gravity survey with an absolute gravimeter based on atom
interferometry and two relative gravimeters: a classical LaCoste&Romberg (L&R) and a …
