Transforming an initial quantum state into a target state through the fastest possible route—a
quantum brachistochrone—is a fundamental challenge for many technologies based on …

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

Fast and nearly lossless atomic transport, enabled by moving the confining trap, is a
prerequisite for many quantum-technology applications. While theoretical studies of this …

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 …

In this study we investigate the dynamics of tunable spin-orbit-coupled spin-1 Bose-Einstein
condensates confined within a harmonic trap, focusing on rapid transport, spin manipulation …

We design faster-than-adiabatic state transfers (switching of quantum numbers) in time-
dependent coupled-oscillator Hamiltonians. The manipulation to drive the process is found …

Interactions between a source of light and atoms are ubiquitous in nature. The study of them
is interesting on the fundamental level as well as for applications. They are at the core of …

Controlling the motional state of a particle in a multidimensional space is key for
fundamental science and quantum technologies. Applying a recently found two-dimensional …

In this work, we study the counterdiabatic (CD) driving scheme and population transfer in
pseudo-and antipseudo-Hermitian systems. By discussing the adiabatic condition for non …

We inverse engineer fast rotations of a transversally tight, linear trap with two ions for a
predetermined rotation angle and time, avoiding final excitation. Different approaches are …
