Reversible logic is became a very promising logic for low power in emerging computing technologies. Reversible logic found applications in ultra-low power green computing, quantum computing, nanotechnology, optical computing, Quantum-dot Cellular Automata (QCA) and dissipation less computing. In the reversible logic there is a one to one mapping between the input and output vectors. The important cost metrics of reversible logic circuits are the quantum cost, the delay and the number of garbage outputs. Garbage outputs are the unutilized outputs, which exists for maintaining the reversibility but do not perform any useful operations.
