Abstract

Quantum-dot Cellular Automata (QCA) is attracting a lot of attentions due to its extremely small feature sizes and ultra low power consumption. Up to now several designs using QCA technology have been proposed. However, we found not all of the designs function properly. Further, no general design guidelines have been proposed so far. A straightforward extension of a simple functional design pattern may fail. This makes designing a large scale circuits using QCA technology an extremely time-consuming process. In this paper we show several critical vulnerabilities in the structures of primitive QCA gates and QCA interconnects, and propose a disciplinary guideline to prevent any additional plausible but malfunctioning QCA designs. copyright
