Overcoming the scale-up challenges of sapphire-based quantum processors

Left: Josephson junctions fabricated in radial pattern around where it was going to be micro-machined later. Right: JJs located <100 micrometre away from the drilling edge were measured and found to be functional. Considering the difficulty of successfully getting a proper connection from an approx 15 micrometre sized probe on such a small area of the remaining contact pad it is remarkable that the JJs worked when so close to a machining process and all that it entails.
