Power generator driven by Maxwell's demon

Nature Communications, 2017
Maxwell’s demon is an imaginary entity that reduces the entropy of a system and generates free energy in the system. About 150 years after its proposal, theoretical studies explained the physical validity of Maxwell’s demon in the context of information ...

Enhanced Photonic Maxwell's Demon with Correlated Baths [PDF]

Quantum, 2021
Maxwell's Demon is at the heart of the interrelation between quantum information processing and thermodynamics. In this thought experiment, a demon generates a temperature gradient between two thermal baths initially at equilibrium by gaining information

Autonomous Dissipative Maxwell’s Demon in a Diamond Spin Qutrit [PDF]

PRX Quantum, 2021
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. Here,

Maxwell's demon across the quantum-to-classical transition [PDF]

Physical Review Research
In 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.

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-

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 analysed theoretically in term 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, 2021
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 ...

All Shook Up: Fluctuations, Maxwell’s Demon and the Thermodynamics of Computation

Entropy, 2013
The most successful exorcism of Maxwell’s demon is Smoluchowski’s 1912 observation that thermal fluctuations would likely disrupt the operation of any molecular-scale demonic machine.

Maxwell's Demon - A Historical Review

Entropy, 2017
For more than 140 years Maxwell’s demon has intrigued, enlightened, mystified, frustrated, and challenged physicists in unique and interesting ways.
