Autonomous Dissipative Maxwell’s Demon in a Diamond Spin Qutrit [PDF]
PRX Quantum, 2022 Engineered dynamical maps combining coherent and dissipative transformations of quantum states with quantum measurements have demonstrated a number of technological applications, and promise to be a crucial tool in quantum thermodynamic processes.

A Programmable Mechanical Maxwell’s Demon [PDF]
Entropy, 2019 We introduce and investigate a simple and explicitly mechanical model of Maxwell’s demon—a device that interacts with a memory register (a stream of bits), a thermal reservoir (an ideal gas) and a work reservoir (a mass that can be lifted or ...

Sorting ultracold atoms in a three-dimensional optical lattice in a realization of Maxwell’s demon [PDF]
Nature, 2018 In 1872, Maxwell proposed his famous ‘demon’ thought experiment1. By discerning which particles in a gas are hot and which are cold, and then performing a series of reversible actions, Maxwell’s demon could rearrange the particles into a manifestly lower-

Genomic-Thermodynamic Phase Synchronization: Maxwell's Demon-like Regulation of Cell Fate Transition. [PDF]
Int J Mol SciDynamic criticality - the balance between order and chaos - is fundamental to genome regulation and cellular transitions. In this study, we investigate the distinct behaviors of gene expression dynamics in MCF-7 breast cancer cells under two stimuli ...

Maxwell's demon across the quantum-to-classical transition [PDF]
Physical Review ResearchIn scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain.

Measurement-Based Quantum Thermal Machines with Feedback Control [PDF]
Entropy, 2023 We investigated coupled-qubit-based thermal machines powered by quantum measurements and feedback. We considered two different versions of the machine: (1) a quantum Maxwell’s demon, where the coupled-qubit system is connected to a detachable single ...

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 ...
