The theory of reversible computing is based upon composition of invertible primitives. In a conventional computer the computation is locally organized around computing primitives, such as the NAND gate, which are noninvertible. Thus, when performing the AND operation a certain amount of information about the system's past is generally erased. This loss of information or damping associated with an irreversible process must be acc9mpanied by the thermalization of an amount kg of energy per bit. Interest in reversible computation thus arises from the desire to reduce heat dissipation in computing circuits, thereby allowing higher density and speed.
