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…

Hidden Dissipation and Irreversibility in Maxwell’s Demon
TLDR
The transport fluxes of mass, momentum, and energy involved in the demon's operation are analyzed and show that they imply "hidden" external work and dissipation, indicating one mechanism by which macroscopic irreversibility may emerge from microscopic dynamics.

TLDR
This chapter examines in detail Landauer's influential argument that erasure of information is a fundamental source of energy dissipation in computation, and concludes that the thermodynamics of computation is a contradiction in terms.

Demons: Maxwell's demon, Szilard's engine and Landauer's erasure-dissipation
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
Experimental verification of Landauer’s principle linking information and thermodynamics
TLDR
It is established that the mean dissipated heat saturates at the Landauer bound in the limit of long erasure cycles, demonstrating the intimate link between information theory and thermodynamics and highlighting the ultimate physical limit of irreversible computation.
All Shook Up: Fluctuations, Maxwell's Demon and the Thermodynamics of Computation
TLDR
A new argument concerning conservation of phase space volume shows that all Maxwell’s demons must fail.
Energy requirement of control: Comments on Szilard's engine and Maxwell's demon
In mathematical physical analyses of Szilard's engine and Maxwell's demon, a general assumption (explicit or implicit) is that one can neglect the energy needed for relocating the piston in Szilard's
Comments on the breakdown of the Landauer bound for information erasure in the quantum regime
Upon reviewing the article by Allahverdyan and Nieuwenhuizen in PRE, we conclude that neither the Landauer principle nor the counterexamples presented by the authors have any relation (i) to
Stability versus reversibility in information processing
The paper is motivated by the discussion of feasibility of large scale quantum computations which should incorporate both unitarity of quantum dynamics for information bearing degrees of freedom and
Irreversibility and heat generation in the computing process
TLDR
Two simple, but representative, models of bistable devices are subjected to a more detailed analysis of switching kinetics to yield the relationship between speed and energy dissipation, and to estimate the effects of errors induced by thermal fluctuations.
