Abstract

This paper presents the Collapsed Bennett Layout, a general purpose floorplan for reversible quantum-dot cellular automata (QCA) circuits. In order to exploit the full density and speed potential of emerging nanodevices, the principles of reversible computing need to be incorporated into the design of nanoscale circuits and systems. The Collapsed Bennett Layout implements Bennett's algorithm in hardware, allowing any arbitrary logic function to be implemented reversibly in QCA.
