Serial Adder using Reversible Gates

Abstract: Reversible logic gates produce zero power dissipation under ideal conditions. Hence these are preferred for low-power design applications such as Quantum computing and Nanotechnology.Adders, Subtractors and Multipliers are basic building blocks of Digital Circuits. This paper proposes design of serial adder using reversible gates. The important reversible gates used for serial adder are Peres gate, Fredkin gate and Feynman gate. The quantum cost of a reversible logic circuit can be minimized by reducing the number of reversible logic gates.
