With the rapid development of modern physics, atomic gyroscopes have been demonstrated
in recent years. There are two types of atomic gyroscope. The Atomic Interferometer …

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 mechanics governs the microscopic world, where low mass and momentum reveal
a natural wave–particle duality. Magnifying quantum behaviour to macroscopic scales is a …

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 …

We simultaneously measure the gravitationally induced phase shift in two Raman-type
matter-wave interferometers operated with laser-cooled ensembles of Rb 87 and K 39 …

Atomic clocks based on laser-cooled atoms are widely used as primary frequency
standards. Deploying such cold atom clocks (CACs) in space is foreseen to have many …

Inertial sensors relying on atom interferometry offer a breakthrough advance in a variety of
applications, such as inertial navigation, gravimetry or ground-and space-based tests of …

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 …

Albert Einstein's insight that it is impossible to distinguish a local experiment in a “freely
falling elevator” from one in free space led to the development of the theory of general …

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