Classical computing machines using irreversible logic gates unavoidably generate heat. This is due to the fact that each loss of one bit of information is accompanied by an increase of the environment’s entropy by an amount k log(2), where k is Boltzmann’s constant. In turn this means that an amount of thermal energy equal to kT log(2) is transferred to the(More)
Reversible logic gates of a certain logic width w form a group (isomorphic to the symmetric group of order (2 w )!). Study of the subgroups of this group both teaches us a lot about properties of reversible gates and guides us to synthesize particular circuits. After design, circuits are implemented in prototype silicon chips.
