2 Abstract: Nowadays reversible logic plays an important role in improving technologies like CMOS design, quantum computing and nanotechnology. In this paper we propose a 4-bit nanometric reversible numerical comparator circuit, which makes our proposed design more efficient and optimal. The major constraint in designing the reversible logic circuit is reducing the number of gates, Garbage outputs and quantum cost. Therefore, we have tried to reduce these parameters to have the most optimal circuit. Compared to its counterpart, our proposed circuit can be reported as improved and well-designed.
