reversal in superconducting meta-atoms induced by picosecond unipolar pulses of a magnetic field is developed. A promising scheme based on the regime of stimulated Raman Λ-type transitions between qubit states via upper-lying levels is suggested in order to provide ultrafastquantumoperations on the
picosecond time scale. The experimental realization of a circuit-on-chip for the discussed ultrafast control is presented.
