Dual control active superconductive devices
A dual control active superconducting device is described comprising; (a) a first device having a first main conduction channel formed of a film of superconductor on a substrate, an active weak link region interposed in the first main conduction channel, the active weak link region composed of a plurality of links formed of a thin film of superconductor separated by non-superconductive voids, the thickness and lateral dimensions of the links selected such that magnetic flux can propagate across the weak link region when it is superconducting, and a first control line having a portion adjacent to the active weak link region of the first main conduction channel such that current in the first control line will impose a magnetic flux on the weak link region; (b) a second superconducting device having a second main conduction channel formed of a film of superconductor on a substrate, an active weak link region interposed in the second main conduction channel, the active weak link region composed of at least one link formed of a thin film of superconductor separated by non-superconductive voids, the thickness and lateral dimensions of the links selected such that magnetic flux can propagate across the weak link region when it is superconducting, and a second control line having a portion adjacent to the active weak link region such that current in the second control line will impose a magnetic flux on the weak link region in the second main conduction channel; (c) an internal control line electrically connected to receive the current passed through the first main conduction channel and having a portion adjacent to the active weak link region of the second main conduction channel such that a current in the internal control line will impose a magnetic flux on the weak link region; and (d) electrical connectors connected to provide input current to the first and second main conduction channels and to conduct the output current.
