We present an experimental realization of an autonomous Maxwell's demon, which extracts microscopic information from a system and reduces its entropy by applying feedback. It is based on two capacitively coupled single-electron devices, both integrated on the same electronic circuit. This setup allows a detailed analysis of the thermodynamics of both the demon and the system as well as their mutual information exchange. The operation of the demon is directly observed as a temperature drop in…

Thermodynamics and efficiency of an autonomous on-chip Maxwell’s demon
TLDR
A detailed analysis of the system and the Demon is presented, including the second law of thermodynamics for bare and coarse grained entropy production and the flow of information as well as efficiency of information production and utilization.
A Maxwell Demon Model Connecting Information and Thermodynamics
In the past decades several theoretical Maxwell's demon models have been proposed to exhibit effects such as refrigerating, doing work at the cost of information, and some experiments have been
Maxwell's demons realized in electronic circuits
Abstract We review recent progress in making the former gedanken experiments of Maxwell's demon [1] into real experiments in a lab. In particular, we focus on realizations based on single-electron
Autonomous quantum Maxwell's demon based on two exchange-coupled quantum dots.
TLDR
The calculated entropy production in a single subsystem and information flow between the subsystems are shown to obey a local form of the second law of thermodynamics, similar to the one previously derived for classical bipartite systems.
Maxwell's demon in a double quantum dot with continuous charge detection
Converting information into work has during the last decade gained renewed interest as it gives insight into the relation between information theory and thermodynamics. Here we theoretically
Experimental Rectification of Entropy Production by Maxwell's Demon in a Quantum System.
TLDR
This realization provides experimental evidence that the irreversibility in a nonequilibrium dynamics can be mitigated by assessing microscopic information and applying a feed-forward strategy at the quantum scale.
Reversing the Landauer's erasure: Single-electron Maxwell's demon operating at the limit of thermodynamic efficiency
According to Landauer's principle, erasure of information is the only part of a computation process that unavoidably involves energy dissipation. If done reversibly, such an erasure generates the
Power generator driven by Maxwell's demon
TLDR
It is demonstrated that Maxwell's demon can generate and output electric current and power with individual randomly moving electrons in small transistors and suggests that evolving transistor-miniaturization technology can increase the demon's power output.
Nonequilibrium System as a Demon.
TLDR
This work demonstrates that it is sufficient to exploit a nonequilibrium distribution to seemingly break the second law of thermodynamics, and proposes both an electronic and an optical implementation of this phenomenon.
Autonomous conversion of information to work in quantum dots
We consider an autonomous implementation of Maxwell's demon in a quantum dot architecture. As in the original thought experiment, only the second law of thermodynamics is seemingly violated when
