Thermodynamics and Energy


Demons: Maxwell’s Demon, Szilard’s Engine and Landauer’s Erasure–dissipation

Authors: Laszlo B. Kish, Claes-Goran Granqvist, Sunil Khatri, He Wen

This talk addressed the following questions in the public debate at HoTPI: (i) energy dissipation limits of switches, memories and control; (ii) whether reversible computers are possible, or does their concept violate thermodynamics; (iii) Szilard’s engine, Maxwell’s demon and Landauer’s principle: corrections to their exposition in the literature; (iv) whether Landauer’s erasure–dissipation principle is valid, if the same energy dissipation holds for writing information, or if it is invalid; and (v) whether (non-secure) erasure of memories, or the writing of the same amount of information, dissipates most heat.
