What if a logic state was distinguished not by the flow of electrons, but by their individual positions? It’s not science fiction. It’s an area of research called quantum cellular automata (QCA), which is part of a quest to find the successor to the aging field effect transistor (FET) as well as a solution to the density versus power dissipation problem that occurs at molecular geometries. In fact, this technology may be the next revolutionary change in the semiconductor industry.
