Nonequilibrium thermodynamics of a superconducting Szilard engine [PDF]
New Journal of PhysicsWe implement a Szilard engine using a 2-bit logical unit consisting of inductively coupled quantum flux parametrons—Josephson-junction superconducting circuits with applications in both the classical and quantum information processing regimes.

Quantum Szilard Engine with Attractively Interacting Bosons [PDF]
Physical Review Letters, 2018 We show that a quantum Szilard engine containing many bosons with attractive interactions enhances the conversion between information and work. Using an ab initio approach to the full quantum-mechanical many-body problem, we find that the average work ...

Bosonic Szilard engine assisted by Feshbach resonances [PDF]
Physical Review A, 2018 It was recently found that the information-to-work conversion in a quantum Szilard engine can be increased by using a working medium of bosons with attractive interactions.

Partially observable Szilárd engines [PDF]
New Journal of Physics, 2022 Almost a century ago, Leo Szilárd replaced Maxwell’s ‘demon’ by machinery. The resulting information engine concept laid the foundation for studying the physical nature of information. Szilárd reduced the demon’s role to mapping an observable onto a work

Coarse-grained Entropy Balance of the Szilard Engine [PDF]
Foundations of PhysicsIn order to reconcile the entropy reduction of a system through external interventions that are linked to a measurement with the second law of thermodynamics, there are two main proposals: (i) The entropy reduction is compensated by the entropy increase ...

Deep reinforcement learning for quantum Szilard engine optimization [PDF]
Physical Review A, 2019 Machine learning techniques based on artificial neural networks have been successfully applied to solve many problems in science. One of the most interesting domains of machine learning, reinforcement learning, has natural applicability for optimization ...

A Modified Szilard's Engine: Measurement, Information, and Maxwell's Demon [PDF]
Entropy, 2004 : Using an isolated measurement process, I've calculated the effect measurement has on entropy for the multi-cylinder Szilard engine. This calculation shows that the system of cylinders possesses an entropy associated with cylinder total energy states ...

Non-equilibrium dynamics of the piston in the Szilard engine [PDF]
EPL (Europhysics Letters), 2018 We consider a Szilard engine in one dimension, consisting of a single particle of mass m, moving between a piston of mass M and a heat reservoir at temperature T.

New Journal of Physics, 2016 We have found the optimal conditions for work performed by the quantum Szilard engine (SZE) containing multi-particles under isothermal processes with inevitable irreversibility. We define the restorability as the probability that the reversibility of an

A quantum version of the classical Szilard engine
Open Physics, 2014 A reinvention of the classical Maxwel demon was proposed by Szilard around the time quantum mechanics was developed. His model continues to attract great interest, especially quantum versions of it.
