Quantum dot Cellular Automata a review on the new paradigm in computation

摘要

Quantum-dot Cellular Automata (QCA), a transistor-less paradigm is a compeer to the existing Complementary metal Oxide Semiconductor (CMOS) technology. The existing CMOS technology has to be mapped to quantum dot paradigm to create QCA structures that can be used to perform all the logic operations which are currently performed by the existing technology. Simple QCA structures that perform all adding and shifting operations were proposed.
