Abstract :
We have investigated the behavior of a quantum cellular automaton cell made up of four quantum dots, in response to the electric field due to a nearby driver cell. We have implemented a simulation based on the single-shot configuration interaction technique, and we have studied the behavior of the cell for a number of electrons variable between 2 and 6. Our results support the conjecture that proper QCA operation can be obtained with a number of electrons per cell corresponding to 4N+2.
