A heat engine model of a reversible computation
Abstract
Using the tools of information theory and thermodynamics, reversible computation at the binary level is modeled as a heat engine operating in a Carnot cycle. The model defines an information-theoretic temperature for a binary system, and predicts that reversible computation can be accomplished without the dissipation of energy. However, in the worst case limit, kT log 2 joules of stored energy per operation per bit are required. Furthermore, T is not the ambient temperature, but the information-theoretic temperature, which for this case is infinite.
