Experimental field data overlaid with the MVTL 2OR-AND circuit. The magnetic field intensity is encoded from 0 (red) to approximately 400 mG (blue). (a)-(c) 3 x 10 micron holes in the superconducting ground plane surrounding the circuit. (d)-(f) broken moat, and (g)-(i) continuous moat with trapped flux. Each image is 400 x 400 microns square and the moats are patterned 2 microns wide surrounding a 137 x 95 micron square area. The continuous moats protect the circuit up to a higher field value than the small holes.
