VLSI technology, although has made remarkable progress in the past, this progress may be slowed down in future. 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).
