Entropy Distribution in a Quantum Informational Circuit of Tunable Szilard Engines [PDF]
Entropy, 2019 This paper explores the possibility of extending the existing model of a single-particle Quantum Szilard Engine to take advantage of some features of quantum information for driving typical mechanical systems. It focuses on devices that output mechanical

Revisiting the quantum Szilard engine with fully quantum considerations [PDF]
Annals of Physics, 2012 By considering level shifting during the insertion process we revisit the quantum Szilard engine (QSZE) with fully quantum consideration. We derive the general expressions of the heat absorbed from thermal bath and the total work done to the environment ...

Biochemical Szilard engines for memory-limited inference [PDF]
New Journal of Physics, 2019 By designing and leveraging an explicit molecular realisation of a measurement-and-feedback-powered Szilard engine, we investigate the extraction of work from complex environments by minimal machines with finite capacity for memory and decision-making ...

Extractable quantum work from a two-mode Gaussian state in a noisy channel [PDF]
Scientific Reports, 2021 We study a Szilard engine based on a Gaussian state of a system consisting of two bosonic modes placed in a noisy channel. As the initial state of the system is taken an entangled squeezed thermal state, and the quantum work is extracted by performing a ...

Mechanical work extraction from an error-prone active dynamic Szilard engine [PDF]
SciPost PhysicsIsothermal information engines operate by extracting net work from a single heat bath through measurement and feedback control. In this work, we analyze a {realistic} active Szilard engine operating on a single self-propelled particle by means of steric ...

Informational Reinterpretation of the Mechanics Notions and Laws [PDF]
Entropy, 2020 The informational re-interpretation of the basic laws of the mechanics exploiting the Landauer principle is suggested. When a physical body is in rest or it moves rectilinearly with the constant speed, zero information is transferred; thus, the ...

On the Precise Link between Energy and Information [PDF]
EntropyWe 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 ...
