- Abstract: This manuscript surveys quantum operations under the influence of harmonic
magnetic fields subject to time variations. The author scrutinises the dynamic
interplay of these fields and canonical variables, leading to effects such as
squeezing, looping effects, and parametric resonances. The time evolution of
observables tethered to a time-dependent quadratic Hamiltonian is examined. The
results of this inquiry offer contributions to the quantum control theory.

We study a model of amplification of quantum transfer and making it directed which we call the quantum ratchet model.
The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels.
Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.
