Much of the power consumed, and heat dissipated, by conventional processors comes from moving information between logic elements rather than the actual logic operations. Because superconductors have zero electrical resistance, little energy is required to move bits within the processor.

That statement in Wikipedia is flat out wrong and notably isn't citing any source.

Incorrect.

This document explains it well. (The resistance of the interconnect is not even mentioned as a significant component of power consumption.)

You can synthesize superconducting FETs though: https://link.springer.com/chapter/10.1007/978-94-011-1918-4_...

Obviously this isn't much benefit since the vast majority of applications can't be liquid nitrogen cooled (and computing has followed "what consumers will buy" on progress).

That changes substantially if superconductors will keep working when put in my pocket.
