Mridula J Deshpande, H. V. Jayashree, V.K. Agrawal · 2017
Reversible gates are gaining popularity in the field of circuit synthesis due to their property of having lower power loss and reduced dissipation of power as heat. These low power design models need to have better optimization properties. In this paper, we have ventured into the template and rule based optimization process. While most reversible netlists are built using the standard Toffoli gates, the proposed Modified Toffoli Gate has been used to achieve optimization. In this paper, the quantum realization of mixed control Modified Toffoli Gate and negative control Modified Toffoli Gates are proposed. Few templates and rules for transforming the original Toffoli network to the Modified Toffoli network are also proposed. This optimization yields a better quantum cost and gate count when compared to that of it's Toffoli counterpart.
