In modern VLSI systems power dissipation is very high due to rapid switching of internal signals. It has been shown that for every bit of information lost in logic computations that are not reversible, kTlog2 joules of heat energy is generated, where k is Boltzmann's constant and T the absolute temperature at which computation is performed. A new reversible logic gate was proposed in ref. This gate can be used to implement any classical Boolean logic function.
