An promising technology that provides a very efficient computational platform than CMOS is a nanotechnology approach i.e. Quantum cellular automata (QCA). It represents the digital information by polarization of electrons. It is attractive for its size, faster speed, feature, highly scalable, higher switching frequency and low power consumption compared to CMOS technology. In near future QCA can take over CMOS because of its significant benefits. This paper mainly projects the implementation and simulation results of various logic gates using quantum dot cellular automata (QCA) designer. Further complex designs can be carried out using these design methodologies. Comparative analysis of QCA design and CMOS is carried to measure performance analysis in terms of covered area (size).
