Harnessing Maxwell's demon to establish a macroscale concentration gradient

J Pruchyathamkorn, BNT Nguyen, AB Grommet… - Nature Chemistry, 2024 - nature.com
Maxwell's demon describes a thought experiment in which a 'demon'regulates the flow of
particles between two adjoining spaces, establishing a potential gradient without appearing …

Szilard engines and information-based work extraction for active systems

P Malgaretti, H Stark - Physical review letters, 2022 - APS
The out of equilibrium nature of active systems can be exploited for the design of information-
based engines. We design two types of an active Szilard engine that use a Maxwell demon …

Optimal performance of a three-stroke heat engine in the microscopic regime

T Biswas, C Datta - Physical Review A, 2024 - APS
We consider a three-stroke engine in the microscopic regime where the working body of the
engine is composed of a two-level system. The working body of the engine aims to withdraw …

Advantage of probabilistic non-gaussian operations in the distillation of single mode squeezed vacuum state

C Kumar - Physica Scripta, 2024 - iopscience.iop.org
We consider distillation of squeezing in single mode squeezed vacuum state using three
different probabilistic non-Gaussian operations: photon subtraction (PS), photon addition …

Catalytic enhancement in the performance of the microscopic two-stroke heat engine

T Biswas, M Łobejko, P Mazurek, M Horodecki - Physical Review E, 2024 - APS
We consider a model of heat engine operating in the microscopic regime: the two-stroke
engine. It produces work and exchanges heat in two discrete strokes that are separated in …

Higher-order process matrix tomography of a passively-stable quantum switch

M Antesberger, MT Quintino, P Walther, LA Rozema - PRX Quantum, 2024 - APS
The field of indefinite causal order (ICO) has seen a recent surge in interest. Much of this
research has focused on the quantum switch, wherein multiple parties act in a superposition …
