A review of QCA adders and metrics
Weiqiang Liu, Maire P. O'Neill, Earl E. Swartzlander · 2012
Quantum-dot Cellular Automata is a potential game changer for integrated circuit design and development. The still evolving technology promises very small, very fast and very low power computation. It differs from current integrated circuit technology in that on chip communication is relatively slow while logic operations are fast. This paper reviews several designs for QCA adders and evaluates them based on newly proposed metrics specific to QCA.
