General Relativity is today the best theory of gravity addressing a wide range of phenomena.
Our understanding of physical laws, from cosmology to local scales, cannot be properly …

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 …

In contrast to light, matter-wave optics of quantum gases deals with interactions even in free
space and for ensembles comprising millions of atoms. We exploit these interactions in a …

The capability to reach ultracold atomic temperatures in compact instruments has recently
been extended into space,. Ultracold temperatures amplify quantum effects, whereas free …

We present the MIGA experiment, an underground long baseline atom interferometer to
study gravity at large scale. The hybrid atom-laser antenna will use several atom …

We report the status of the Cold Atom Lab (CAL) instrument to be operated aboard the
International Space Station (ISS). Utilizing a compact atom chip-based system to create …

Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC)
as well as cold matter in general. Twenty years after the first realization of the BEC and 15 …

Long-distance entanglement is a very precious resource, but its distribution is very difficult
due to the exponential losses of light in optical fibres. A possible solution consists in the use …

Abstract We describe the Quantum Test of the Equivalence principle and Space Time
(QTEST), a concept for an atom interferometry mission on the International Space Station …

Long-term observation of Earth's temporal gravity field with enhanced temporal and spatial
resolution is a major objective for future satellite gravity missions. Improving the performance …
