Death of the "standard" microprocessor? (Score 1)

My question is, as we improve nanotechnology, eventually we hit a point where we can no longer go any smaller (the use of single molecules as gates, for example). After we reach the point where it is impossible to shrink circuits any smaller, where will we go from there? So far, the only work I've heard of in this direction is the "quantum computer," and that is still in the theoretical stage. Does anyone know of any other technologies that we may switch to when our current methods of chip design simply can not become any smaller?
