# Critical remarks on Landauer's principle of erasure-dissipation: Including notes on Maxwell demons and Szilard engines

@article{Kish2015CriticalRO, title={Critical remarks on Landauer's principle of erasure-dissipation: Including notes on Maxwell demons and Szilard engines}, author={Laszlo B. Kish and Sunil P. Khatri and Claes G{\"o}ran Granqvist and Janusz M. Smulko}, journal={2015 International Conference on Noise and Fluctuations (ICNF)}, year={2015}, pages={1-4} }

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…
