ABSTRACT:
A superconducting element includes a superconducting thin film bridge extending along the surface of a substrate, and a control electrode member for injecting quasi particles into a portion of an intersection region of the superconducting thin film bridge. The intersection region extends across the superconducting thin film bridge in a direction which is perpendicular to the current flow direction of the superconducting thin film bridge. A remaining portion of the intersection region, which is not injected with quasi particles by the control electrode member, operates as a weak-coupling bridge to thereby control the current flow within the superconducting thin film bridge.
