"magnetic flux vortice motion generating resistance/ heat limited by thermal dissipation before material reaches intrinsic depairing critical current limit... overcome outrunning slow-moving vortices, unlocking behavior normally obscured during direct-current measurements... performance contrasts between isotropic superconductors (niobium nitride)/ anisotropic high-temperature superconductors (YBCO)... limits linked to internal energy gap structures... probing/ controlling high-performance quantum circuits"
