Abstract :
A shift register prototype has been implemented with lead-alloy technology. Single-flux quanta have been shifted in both directions by local magnetic fields with a maximum repetition frequency of 250 MHz. The absence or presence of a flux quantum at a given position is read out nondestructively. The speed and the miniaturisation potential of the proposed shift register is discussed.
