Throughout the last decade, reversible logic has been an emerging research topic. Over the years, a considerable number of application specific new reversible gates with varied characteristics have been proposed. Barring few, most of the gates lack fundamental quantum mapping in contemporary literature. This paper takes into account the four variable reversible gates those have been proposed and provides the Toffoli mapping using positive control lines. The authors optimize the designs using negative control lines wherever possible. The quantum cost, quantum gate count and two-qubit gate count required to implement those reversible gates have been provided which will set a benchmark for optimized gate choice for complex Boolean realizations. The authors also provide Hamming Distance based Complexity analysis.
