It is known that high intensity fields are usually required to implement shortcuts to
adiabaticity via transitionless quantum driving (TQD). Here, we show that this requirement …

Shortcuts to adiabaticity provide a general approach to mimic adiabatic quantum processes
via arbitrarily fast evolutions in Hilbert space. For these counter-diabatic evolutions, higher …

Adiabatic operations are powerful tools for robust quantum control in numerous fields of
physics, chemistry, and quantum information science. The inherent robustness due to …

We introduce a new approach for describing nonstationary quantum systems with a discrete
energy spectrum. The essence of this approach is that we describe the evolution of a …

We investigate a system of two identical and distinguishable spins 1/2, with a direct
magnetic dipole–dipole interaction, in an external magnetic field. Constraining the hyperfine …

We develop an effective scheme for implementing error-insensitive population transfer in a
three-level system (qutrit) by invariant-based shortcuts with optimized drivings. Based on the …

We propose a method to describe the evolution of two spins coupled by hyperfine interaction
in an external timedependent magnetic field. We apply the approach to the case of hyperfine …

Effective Hamiltonian engineering is a powerful technique that utilises time-dependent
perturbation theory to suppress or enhance certain effects that arise from otherwise weak …

An analytical solution is obtained for the problem of two interacting, identical but separated
spin 1/2 particles in a time-dependent external magnetic field, in a general case. The …
