Critical Remarks on Landauer's Principle of Erasure-Dissipation Including Notes on Maxwell Demons and Szilard Engines Conference Paper uri icon

abstract

  • © 2015 IEEE. We briefly address Landauer's Principle and some related issues in thermal demons. We show that an error-free Turing computer works in the zero-entropy limit, which proves Landauer's derivation incorrect. To have a physical logic gate, memory or information-engine, a few essential components necessary for the operation of these devices are often neglected, such as various aspects of control, damping and the fluctuation-dissipation theorem. We also point out that bit erasure is typically not needed or used for the functioning of computers or engines (except for secure erasure).
