  • 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 operation per bit are required, where T is not the ambient temperature but the information-theoretic temperature, which for this case is infinite
