BIDIRECTIONAL LASER TUNING OF JOSEPHSON JUNCTIONS

This abstract first appeared for US patent application 18501196 titled 'BIDIRECTIONAL LASER TUNING OF JOSEPHSON JUNCTIONS

Original Abstract Submitted

A calibration process comprises performing laser annealing calibration operations on first Josephson junctions using different combinations of at least laser power settings and anneal times, determining junction resistance shifts of the first Josephson junctions as a result of the laser annealing calibration operations, and utilizing the determined junction resistance shifts of the first Josephson junctions to determine calibration data for configuring laser annealing operations for bidirectional laser tuning of second Josephson junctions corresponding to the first Josephson junctions.
