  • Superconducting microwave switch
    Patent number: 10812073
    Abstract: A microwave switch. In some embodiments, the microwave switch includes a substrate, a signal conductor, a first ground conductor, on a first side of the signal conductor, and a second ground conductor, on a second side of the signal conductor. The signal conductor, the first ground conductor, and the second ground conductor may be planar conductors on a planar top surface of the substrate. The signal conductor may have a first portion composed of a superconducting material, and a second portion having a reduced cross section, a cross-sectional area of the second portion being less than 120 nm.
    Type: Grant
