A Novel Full Adder Implementation Using Quantum Cellular Automata
Guo Liu · 2005
Based on the bistable saturation in quantum cellular automata and the concepts of digital circuits,exclusive-OR gate and full adder are constructed which composed of quantum cellular automata.Semiclassical simulation of quantum cellular automaton circuits is employed to simulate the circuits. We compare the novel circuits we designed with the circuits constructed by Tougaw et al,and results show that the novel circuits possess more simple architecture and fewer number of QCA cells and the scale of the novel circuits is only half of the scale of the circuits constructed by Tougaw.It can be used for reference to minimize the scale of the more complex circuits designed in the future.
