Designing Ultra-Dense Computers with QCAs
"A Potential Quantum Leap in Computing"

Problem: Most projections of CMOS technologies perceive an ultimate limit of about 0.05 micron feature sized devices in about 10 years."

The QCA Solution: Utilize a new technology termed Quantum Cellular Automata (QCA) to build real computers orders of magnitude denser than the limits of CMOS from molecularly sized devices where information is moved by Coulombic interactions rather than current flow.
