With the advances in nanoscale fabrication and control, new kinds of nanoscale devices can now be considered. One promising example has been quantum dot cellular automata where the locations of just one or two charges can be used to represent 0 or 1 for the basic building block for logic devices. We have been considering a similar approach with superconducting vortices in nanostructured arrays to creat vortex cellular automata. In addition to new types of logic circuits, we have also been considering new types of mechanical devices such as gears. In addition to the technological applications, there are also many scientific issues that we are exploring in these systems such as using various types of deterministic ratchets for soliton propagation.
