  We designed and experimentally demonstrated a four-terminal superconducting
device which can function as a non-latching (reversible) superconducting switch
from the diode regime to the resistive state by applying a control current much
smaller than the main transport current. The device utilizes a vortex-based
superconducting diode mechanism which is switched back and forth via the
injection of flux quanta through auxiliary current leads. Various applications
in superconducting electronics can be foreseen.
