Abstract

A kinetic inductance travelling-wave parametric amplifier (KTWPA) device is provided that includes a metallic enclosure (302) having a base including an inside top surface, sides, and an enclosure lid (308), a substrate (402) coupled to the inside top surface of the base, the substrate including a plurality of conductive pads (206), a silicon die (202) including a superconducting transmission line (200), the silicon die coupled to the substrate, a plurality of conductive spacers (210) coupled to the silicon die, wire bonds (208) attached between the conductive pads and the silicon die, and a copper lid (212) coupled to the top end of the plurality of conductive spacers, where the copper lid is electrically and thermally coupled to the enclosure lid. The KTWPA device may be applied in a quantum microwave measurement circuit to amplify a quantum measurement signal from a quantum circuit.
