Quantum-dot cellular automata (QCA) is considered as an advanced technology compared to complimentary metal-oxide-semiconductor (CMOS) due to QCA’s merits.Many logical circuits are designed using QCA which consume low power.Therfore our interest is on desiging of adders using QCA. In this paper we present a number of new results on adders.Thus we design adders and detailed simulation using QCAD designer is presented.The performance of proposed adder gives the better Delay performance compared to Ripple carry adder(RCA).Thus we show that Brent-kung Adder has lower Delathen most of the proposed advanced adders.
