  We demonstrate non-adiabatic charge pumping utilizing a sequence of coherent
oscillations between a superconducting island and two reservoirs. Our method,
based on pulsed quantum state manipulations, allows to speedup charge pumping
to a rate which is limited by the coupling between the island and the
reservoirs given by the Josephson energy. Our experimental and theoretical
studies also demonstrate that relaxation can be employed to reset the pump and
avoid accumulation of errors due to non-ideal control pulses.
