Quantum optimal control, a toolbox for devising and implementing the shapes of external
fields that accomplish given tasks in the operation of a quantum device in the best way …

Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

Owing to the low-gravity conditions in space, space-borne laboratories enable experiments
with extended free-fall times. Because Bose–Einstein condensates have an extremely low …

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 …

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 …

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 …

We study a space-based gravity gradiometer based on cold atom interferometry and its
potential for the Earth's gravitational field mapping. The instrument architecture has been …

We report on the efficient design of quantum optimal-control protocols to manipulate the
motional states of an atomic Bose-Einstein condensate (BEC) in a one-dimensional optical …

Shortcuts to Adiabaticity (STA) constitute driving schemes that provide an alternative to
adiabatic protocols to control and guide the dynamics of classical and quantum systems …
