A method for manipulating a quantum system comprises at least one mobile charge carrier with a magnetic moment. The method comprises the steps or acts of applying magnetic field to the charge carrier. The magnetic is spatially non-homogeneous. The method also comprises bringing the charge carrier into an oscillatory movement along a path. The magnetic field depends on the position of the charge carrier on said path. The oscillatory movement may be caused by electrostatic interaction with gate electrodes. Due to this approach, thus, in a magnetic moment resonance process the conventional oscillating magnetic field is replaced by an oscillating electric field which is locally transformed into a magnetic field by the Coulomb interaction that displaces the charge carrier wave function within an inhomogeneous magnetic field or in and out of a magnetic field.
