The reversible logic has the promising applications in emerging computing paradigm
such as quantum computing, quantum dot cellular automata, optical computing, etc. In
reversible logic gates there is a unique one-to-one mapping between the inputs and outputs.
To generate an useful gate function the reversible gates require some constant ancillary
inputs called ancilla inputs. Also to maintain the reversibility of the circuits some additional
unused outputs are required that are referred as the garbage outputs. The number of
ancilla inputs, number of garbage outputs and quantum cost plays an important role in
the evaluation of reversible circuits. Thus minimizing these …
