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.

基于组态交互的量子元胞自动机模拟
我们研究了由四个量子点组成的量子元胞自动机细胞对附近驱动细胞产生的电场的响应行为。我们实现了基于单次组态相互作用技术的模拟,并研究了电子数在2和6之间变化时电池的行为。我们的结果支持这样的猜想,即每个电池对应4N+2的电子数可以获得适当的QCA操作。
