Abstract
A Josephson junction (JJ) quantum bit (qubits) arranged on a substrate is provided. In one embodiment, each qubit comprises a dielectric layer, a superconductor base layer portion underlying the dielectric layer and a first dielectric diffused region adjacent a dielectric layer/superconductor base layer portion junction. The qubit further comprise a superconductor mesa layer portion overlying the dielectric layer and having a second dielectric diffused region adjacent a dielectric layer/superconductor mesa layer portion junction, the first and second dielectric diffused regions mitigating further diffusion from other semiconductor processes on the plurality of qubits.
