Abstract

See full text

Methods are provided of forming a Josephson junction (JJ) quantum bit (qubit). In one embodiment, the method comprises forming a JJ trilayer on a substrate. The JJ trilayer is comprised of a dielectric layer sandwiched between a bottom superconductor material layer and a top superconductor material layer. The method further comprises performing a thermal hardening process on the JJ trilayer to control diffusion of the dielectric layer into the bottom superconductor material layer and the top superconductor material layer, and etching openings in the JJ trilayer to form one or more JJ qubits.
