Cross-section schematic of the superconductorinsulatorsuperconductor JJ at the location indicated by the dash-dotted line in a. The supercurrent I n ( ) of each conduction channel n = 1, , N depends on its transparency T n (equation ( 2 )). We sketch a distribution of multiple low and a few high transparencies T 1 , , T N in green and red, respectively.
