The model of digital computation used until now is intrinsically irreversible. This is because the two-bit gates used to construct circuits are irreversible as they involve two input bits and only one output bit. Irreversible gates dissipates energy during their operations, in this manner information bits are lost. Reversible Logic (RL) is a technique that can lead to circuits run as normal Logic operations, but use less power. In reversible logic the number of inputs and number of outputs must be equal. The input states are reconstructed from output states because of one to one mapping.
