  • JOSEPHSON JUNCTION DEVICE WITH ORTHOGONAL ELECTRODES
    Publication number: 20260130127
    Abstract: A Josephson junction (JJ) device is disclosed that includes a first superconductor structure having a bottom superconductor arm portion and a second superconductor structure having a top superconductor arm portion disposed substantially orthogonal to the bottom superconductor arm portion and overlapping the bottom superconductor arm portion in a JJ operation region. The JJ device further includes a dielectric material layer acting as a tunnel barrier disposed between the bottom superconductor arm portion and the top superconductor arm portion in the JJ operation region to form an operating JJ.
    Type: Application

  • Josephson junction device and method of making the same
    Patent number: 12604673
    Abstract: A Josephson junction (JJ) device is provided. The JJ device comprises an operating JJ, a first hydrogen-trapping JJ having a first end coupled to a first end of the operating JJ and a second end coupled to a first superconductor wire, and a second hydrogen-trapping JJ having a first end coupled to a second end of the operating JJ and a second end coupled to a second superconductor wire. The first hydrogen-trapping JJ and the second hydrogen-trapping JJ mitigates hydrogen diffusion into the operating JJ.
