Landauer’s Principle in a Quantum Szilard Engine without Maxwell’s Demon [PDF]

open access: yesEntropy, 2020
Quantum Szilard engine constitutes an adequate interplay of thermodynamics, information theory and quantum mechanics. Szilard engines are in general operated by a Maxwell’s Demon where Landauer’s principle resolves the apparent paradoxes ...

Endoreversible Models for the Thermodynamics of Computing [PDF]

open access: yesEntropy, 2020
Landauer’s principle says that, in principle, a computation can be performed without consumption of work, provided no information is erased during the computational process. This principle can be introduced into endoreversible models of thermodynamics.

On the Precise Link between Energy and Information [PDF]

open access: yesEntropy
We present a modified version of the Szilard engine, demonstrating that an explicit measurement procedure is entirely unnecessary for its operation. By considering our modified engine, we are able to provide a new interpretation of Landauer’s original ...

Minimising the heat dissipation of quantum information erasure

open access: yesNew Journal of Physics, 2016
Quantum state engineering and quantum computation rely on information erasure procedures that, up to some fidelity, prepare a quantum object in a pure state.

Landauer Principle and the Second Law in a Relativistic Communication Scenario [PDF]

open access: yesEntropy
The problem of formulating thermodynamics in a relativistic scenario remains unresolved, although many proposals exist in the literature. The challenge arises due to the intrinsic dynamic structure of spacetime as established by the general theory of ...

On the Supposed Mass of Entropy and That of Information [PDF]

open access: yesEntropy
In the theory of special relativity, energy can be found in two forms: kinetic energy and rest mass. The potential energy of a body is actually stored in the form of rest mass, the interaction energy too, but temperature is not.

Algorithmic Entropy and Landauer’s Principle Link Microscopic System Behaviour to the Thermodynamic Entropy [PDF]

open access: yesEntropy, 2018
Algorithmic information theory in conjunction with Landauer’s principle can quantify the cost of maintaining a reversible real-world computational system distant from equilibrium. As computational bits are conserved in an isolated reversible system,

Information Dark Energy Can Resolve the Hubble Tension and Is Falsifiable by Experiment [PDF]

open access: yesEntropy, 2022
We consider the role information energy can play as a source of dark energy. Firstly, we note that if stars and structure had not formed in the universe, elemental bits of information describing the attributes of particles would have exhibited properties

Evidence for Dark Energy Driven by Star Formation: Information Dark Energy? [PDF]

open access: yesEntropy
Evidence is presented for dark energy resulting directly from star formation. A survey of stellar mass density measurements, SMD(a), as a function of universe scale size a, was found to be described by a simple CPL w0 − wa parameterisation that was in ...

Finite-time Landauer principle beyond weak coupling [PDF]

open access: yesQuantum, 2023
Landauer's principle gives a fundamental limit to the thermodynamic cost of erasing information. Its saturation requires a reversible isothermal process, and hence infinite time.
