Abstract

This paper presents the novel design of half adder and full adder using reduced number of QCA gates. This design utilizes the unique characteristics of QCA to design a half and a full adder. The basic component of QCA is a cell consisting of two electrons and four logically interacting quantum dots. Simulation indicates a fast,efficient and very attractive performance(i. e. complexity,area and delay)
