Physical Review Letters, 1999 We consider a dilute gas of granular material inside a box, kept in a stationary state by shaking. A wall separates the box into two identical compartments, save for a small hole at some finite height $h$.

A quantum-mechanical Maxwell's demon [PDF]
Physical Review A, 1996 A Maxwell's demon is a device that gets information and trades it in for thermodynamic advantage, in apparent (but not actual) contradiction to the second law of thermodynamics.

Extracting Work from Quantum Measurement in Maxwell’s Demon Engines [PDF]
Physical Review Letters, 2017 The essence of both classical and quantum engines is to extract useful energy (work) from stochastic energy sources, e.g., thermal baths. In Maxwell's demon engines, work extraction is assisted by a feedback control based on measurements performed by a ...

Information Gain and Loss for a Quantum Maxwell’s Demon [PDF]
Physical Review Letters, 2018 We use continuous weak measurements of a driven superconducting qubit to experimentally study the information dynamics of a quantum Maxwell's demon. We show how information gained by a demon who can track single quantum trajectories of the qubit can be ...

Autonomous Maxwell's demon in a cavity QED system [PDF]
Physical Review Research, 2020 We present an autonomous Maxwell's demon scheme. It is first analyzed theoretically in terms of information exchange in a closed system and then implemented experimentally with a single Rydberg atom and a high-quality microwave resonator.

Beating the Thermal Limit of Qubit Initialization with a Bayesian Maxwell’s Demon [PDF]
Physical Review X, 2022 Fault-tolerant quantum computing requires initializing the quantum register in a well-defined fiducial state. In solid-state systems, this is typically achieved through thermalization to a cold reservoir, such that the initialization fidelity is ...

Maxwell’s Demon Is Foiled by the Entropy Cost of Measurement, Not Erasure
FoundationsI dispute the conventional claim that the second law of thermodynamics is saved from a “Maxwell’s demon” by the entropy cost of information erasure and show that instead it is measurement that incurs the entropy cost.

Language Individuation and Marker Words: Shakespeare and His Maxwell's Demon. [PDF]
PLoS ONE, 2013 BACKGROUND:Within the structural and grammatical bounds of a common language, all authors develop their own distinctive writing styles. Whether the relative occurrence of common words can be measured to produce accurate models of authorship is of ...

Electrical Maxwell demon and Szilard engine utilizing Johnson noise, measurement, logic and control. [PDF]
PLoS ONE, 2012 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 circuitry and electronically controlled switches and uses ...
