Connor Shelly - OQC

(a) As-fabricated Josephson junction resistances from a typical OQC Lucy-8QPU wafer. JJ resistances are in three separate design groups 1, 2, and 3, designated by the colours grey, red, and blue. (b) The same wafer having undergone our electron-beam annealing process. The spread of each JJ group is reduced.

E-beam annealing of Josephson junctions offers precise control over qubit frequencies

Electron-beam (e-beam) annealing of Josephson junctions offers precise control over qubit frequencies post-fabrication.
