Programmable reversible logic is growing for a potential logic design type concerning execution around advanced nanotechnology as well as quantum computing with minimum effect upon circuit temperature production. Current improvements in reversible logic utilizing additionally quantum computer calculations permit enhanced computer structure plus arithmetical logic unit layouts. Since reversible circuits continue to be fairly unique, the most significant study effect is found on the synthesis of these circuits. Quantum-dot cellular automata (QCA) can be a promising part of investigating at reversible computing. QCA-based design of the reversible 1-bit full adder is using the Toffoli and Feynman gates have been achieved in this study. We develop an improved reversible full adder with overflow detection to enhance reliability. This component promises to complete the fundamental mathematical functions of addition, subtraction alongside overflow detection, comparison, along with logic procedures such as significance. Thus our design is very efficient and versatile alongside lower quantity of lines as well as quantum cost. This work understands and nurtures the necessity of reversible full adder for future revolutionary computing technologies. In this paper, a reversible 1-bit full adder is proposed and compared with other reversible full adders. Proposed gate performs better than existing methods and ensures maximum logical operations like the full adder, full with less quantum cost where other existing gates are not viable.
