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 engine and for driving the trap door in Maxwell's demon. If this basic assumption is wrong, then the conclusions of a vast literature on the implications of the second law of thermodynamics and of Landauer's erasure theorem are incorrect, too. Our analyses of the fundamental information physical… Expand

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 doesExpand
Variations on a Demonic Theme: Szilard's Other Engines
TLDR
The analysis of Szilard's remaining two demon models gives insight into designing and implementing novel nanoscale information engines by investigating the relationships between the demon's memory, the nature of the "working fluid," and the thermodynamic costs of erasure and measurement. Expand
Critical remarks on Landauer's principle of erasure-dissipation: Including notes on Maxwell demons and Szilard engines
TLDR
It is shown that an error-free Turing computer works in the zero-entropy limit, which proves Landauer's derivation incorrect, and points out that bit erasure is typically not needed or used for the functioning of computers or engines (except for secure erasure). Expand
Critical remarks on Landauer's principle of erasure-dissipation: Including notes on Maxwell demons and Szilard engines
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 derivationExpand

Electrical Maxwell Demon and Szilard Engine Utilizing Johnson Noise, Measurement, Logic and Control
TLDR
A purely electrical version of Maxwell's demon which does not involve mechanically moving parts and has purely electronic controls and is free of the major weakness of the original Szilard engine in not requiring removal and repositioning the piston at the end of the cycle. Expand

We introduce a purely electrical version of Maxwell’s demon which does not involve mechanically moving parts such as trapdoors, etc. It consists of a capacitor, resistors, amplifiers, logic circuitryExpand
An autonomous and reversible Maxwell's demon
Building on a model introduced by Mandal and Jarzynski (Proc. Natl. Acad. Sci. U.S.A., 109 (2012) 11641), we present a simple version of an autonomous reversible Maxwell's demon. By changing theExpand
The Thermodynamics of Computation: A Contradiction
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. Expand

TLDR
The argumentation is invalid because it neglects the dominant source of energy dissipation, namely, the charging energy of the capacitance of the input electrode, which totally dissipates during the full (0-1-0) cycle of logic values. Expand
