A reversible gate has the equal number of inputs and outputs and one-to-one mappings between input vectors and output vector, thus the vector of input states can be always reconstructed from the vector of output states. A gate with k inputs and k outputs is called a k*k gate. Reversible logic Gate has one of the most important approaches for the power factor with its application in low power VLSI design. The Quantum computing having with applications in the domains like Nano-technology, Cryptography and Communications. It`s also called as lossless circuits. In this paper addition operation is realized using reversible logic gates like DKG gate. Here we implement 4-Bit Full adder using DKG reversible logic gate.
