I was wondering, what kind of quantum physics knowledge is important in the design and analysis of nanoelectronics? What differences are there between nanocircuits and "normal" circuits? Does Ohm's Law and other well known equations apply in the quantum world?

I'm not one of the guys who works directly with this stuff just one of the guys who translates the design into something that will work on actual manufacturing equipment so 'Yes' (under the right conditions), Ohm's law and basic EM theory works in nano-scale circuits but conductors are not seen as solid wires and must the considered as probability wave plasmas with non-uniform densities so special 'tricks' are necessary to maintain circuit design rules.

How Intel did it.
