    • Test junctions designed at 0.5 μM to 2 μm from the edge of the trilayer showed no measurable change in quality namely the sub-gap leakage. The qubit designs have junctions 2 μm From the Edge of the BE.

    • Similar measurements were made on a DC SQUID with 1 μm Junctions for temperatures down to 30 mK. The distributions agree with TA theory and confirm the empirical relation.
