Numerical investigation of energy dissipation in Quantum Cellular Automaton circuits
Luca Bonci, Massimo Macucci · 2006
We present a numerical study of energy dissipation in the switching process of Quantum Cellular Automaton (QCA) circuits, for both the non clocked and the clocked case. As a reference circuit, we consider binary wires of different lengths, investigating the relationship between the energy delivered by the external voltage sources and the switching speed, the number of cells, and the maximum operating temperature. Finally, we compare the achieved performance with that of different technological approaches.
