Quantum Dot Cellular Automata Based Digital Logic Circuits A Design Using arrays of quantum dots, qca encodes binary information and implements specific logic gates according to the layout of the quantum dots. Current qca alu designs are either irreversible or logically reversible; however, they lack physical reversibility, a crucial requirement to increase energy efficiency.
