The End of the Thermodynamics of Computation: A No Go Result

Abstract Electronic computers generate heat and the need for its removal sets a practical limit to their performance. In thermodynamic terms, the heat arises from the degradation of the work energy supplied electrically to operate the computer. The study of the thermodynamics of computation, surveyed in Bennett (1982), seeks to find the limits in principle to reduction of this dissipation. Since it reduces with the size of the computing device, the most thermodynamically efficient computers are sought among those that use individual molecules, charges or magnetic dipoles as memory storage devices
