Quantum Gates to Implement the Reversible Logic Circuits

Quantum gates which are represented by unitary matrices have potentials to implement the reversible logic circuits. M and M^+ gates are two well-known quantum gates which are used to synthesize the reversible logic circuits. In this work, we have used behavioral description of these gates, instead of unitary matrix description, to synthesize reversible logic circuits. By this method, M and M^+ gates are shown in the truth table form.
