A Novel ASK Reversible Gate and its Implementation in Ripple Carry Adder Design

Reversible logic is gaining increasing significance in diverse research areas, including quantum computing, nanotechnology, and optical computing. The exploration of reversible gates has emerged as a cutting-edge research area, driving a wave of innovative developments aimed at maximizing resource efficiency. Adders are essential in multipliers, especially in digital signal processing (DSP) applications. Reversible logic gates represent a major breakthrough in digital circuit design due to their ability to perform operations without loss. This work presents a novel 4×4 reversible gate and explores its potential in designing highly efficient digital circuits. The study examines the use of the suggested gate in implementing a full adder and a ripple carry adder. The improved efficiency and potential for scalable quantum computing of the new full adder and ripple carry adder designs are illustrated by their superior performance in terms of garbage outputs, ancilla inputs, and quantum cost when compared to the conventional architectures.
