Would superconductors like Graphene or Carbon nanotubes allow for low latency signalling over longer distances?

- ChuckMcM 13y agoNo, its a speed of light issue. Signals can only propagate at the speed of light. The other issue with signals integrity is when a signal goes from one wire to another (like it does through a connector) it behaves a bit like light going through one lens into another. Most of the signal goes through, some of it gets reflected. The result is that instead of the signal being there or not being there (ideal) you end up with what folks think of as any 'eye' pattern (it looks a bit like an eye) which is the point where the signal is reliably all there, or all not there (in digital terms a 1 or 0). More reflections, more noise, the smaller the eye and the harder to reliably read the signal.
