Josephson junction resistance tuning

Abstract

The invention is in the field of superconducting integrated circuits, in particular systems and methods for tuning superconducting integrated circuit elements such as Josephson junctions. A system for simultaneously modifying the resistance of a plurality of Josephson junctions comprises an assembly comprising a plurality of probes configured to be brought into electrical connection with the plurality of Josephson junctions when the system is in use, measurement electronics for measuring a resistance of each of the plurality of Josephson junctions via the plurality of probes, and driving electronics for applying resistance change stimuli to the plurality of Josephson junctions in order to simultaneously modify the resistance of at least a subset of the plurality of Josephson junctions.
