Quantum-dot devices and Quantum-dot Cellular Automata
Journal of the Franklin Institute, 1997 We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. Boolean logic functions may be implemented in specific arrays of cells representing binary information, the so-called Quantum-Dot Cellular Automata (QCA).
