Abstract
Energy dissipation is the important constrain in the design and implementation of VLSI circuits. Usage of Reversible logic circuit is the best solution for lower energy dissipation. In this paper, basic reversible gates and some existing gates and KMD gates are realized using the Quantum Equivalent structure and the Controlled-V and V+ gate structure from their functional expression. Using the qubit gate reduction procedure of quantum circuit, the quantum cost and number of primitive gates of the functional expression are deduced. After synthesizing the Quantum Cost (QC), Gate count (GC), Garbage Output (GO), number of gates, constant inputs are compared with the non-optimized circuit. The quantum circuit and controlled V and V+ structure are realized in RCViewer+ tool using .tfc (“Toffoli-Fredkin Cascade”) code.
