We investigate a time-efficient and robust preparation of spin-squeezed states—a class of
states of interest for quantum enhanced metrology—in internal bosonic Josephson junctions …

In this paper we evaluate the performance of two superadiabatic stimulated Raman
adiabatic passage (STIRAP) protocols derived from Gaussian and sin-cos pulses, under …

Theoretical studies of coherent atom transport have as yet mainly been restricted to one-
dimensional model systems with harmonic trap** potentials. Here we investigate this …

We report on the transport of a thermal cloud of ultracold cesium and rubidium atoms over
about 37 cm in under 25 ms using an optical conveyor belt formed by two …

Shortcuts to adiabaticity are alternative fast processes which reproduce the same final state
as the adiabatic process in a finite or even shorter time, which have been extended from …

The twist-and-turn dynamics of spin squeezing results from the interplay of the one-axis-
twisting (nonlinear in the collective-spin operators) and the transverse-field turning (linear) …

We report on the transport of ultracold cesium and rubidium atoms over $37.2\, $ cm in
under $25\, $ ms using an optical conveyor belt formed by two counter-propagating beams …

Bang-bang control is often used to implement a minimal-time shortcut to adiabaticity for
efficient transport of atoms in a moving harmonic trap. However, drastic changes of the on-off …

With the advent of quantum technologies, control issues are becoming increasingly
important. In this paper, we address control in phase space under a global constraint …

We review methods to shuttle quantum particles fast and robustly. Ideal robustness amounts
to the invariance of the desired transport results with respect to deviations, noisy or …
