Concept of Nanolectronics

Of course it does. The valence electrons always follow the classical Physics laws of Maxwell, Kirchoff, Faraday, etc. They also always follow the quantum Physics of Schroedinger, De Broglie, Heisenberg, etc. The problem comes from people's macroscopic analysis of how the valence electrons should flow are dominated mostly by the classical laws because the quantum effects average out to become just classical laws. At the tiny scale of nano physics one must include the quantum effects that are actually happening because the number of particles interacting are so small that an averaging out of the quantum effects is no longer valid.

This difference may now become an advantage. One may be able to use the quantum effects to fabricate quantum computer circuits. In theory a quantum computer is able to calculate all permutations of a problem truly instantly. I don't mean that the analysis is so fast it seems to us to be instantaneous, all permutations are analyzed in an entangled instant. Nobody has made such a machine. Nobody knows if such a machine can be made at all or if it is just our present fabrication techniques that prevent us from building such a machine.

Getting back to my point though, the electrons still follow the same rules we have observed. Once we get this small though, we can no longer ignore some of these rules in our analysis.
