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 …

Robust excitation of a large spin ensemble is a long-standing problem in the field of
quantum information science and engineering and presents a grand challenge in quantum …

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 …

In this paper, we study the control of a class of time-invariant linear ensemble systems
whose natural dynamics are linear in the system parameter. This class of ensemble control …

In this work we derive ultrafast shortcuts for adiabatic rapid passage for a qubit where the
only control variable is the longitudinal z field, while the transverse x field remains constant …

In this article we consider a bosonic Josephson junction, a model system composed by two
coupled nonlinear quantum oscillators which can be implemented in various physical …

In this note, we use geometric optimal control to completely solve the problem of minimum-
time transitions between thermal equilibrium states of the quantum parametric oscillator …

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 …

In this article we propose a novel method to accelerate adiabatic passage in a two-level
system with only longitudinal field (detuning) control, while the transverse field is kept …

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 …
