Atomic Quantum Dot based Quantum Cellular Automata

It has been discovered that single silicon atoms on an ordinary silicon crystal serve as "quantum dots", enabling control over single electrons and thereby enabling revolutionary computation schemes that consume miniscule power. This new control over electrons may be put to use in a number of ways. For example, the "QCA" (quantum cellular automata) mechanism proposed by Craig Lent and co-workers at Notre Dame provides an architecture for an extremely low power computer.

How fast such computer could get?

[dreymaddox]

that's enourmous!!! what else could this technology be useful for??

i love how CGI graphics can help make such concept so easy to understand
