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 a natural applicability for optimization problems in physics.

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

Two-level system hyperpolarization with a quantum Szilard engine [PDF]
By implementing a quantum Szilard engine, we show that a superconducting granular aluminum fluxonium qubit is coupled weakly to a two-level system (TLS) environment of unknown physical origin. Since the TLSs are much longer lived than the qubit, non-exponential relaxation and non-Poissonian quantum jumps can be observed.

A quantum Szilard engine without heat from a thermal reservoir
New Journal of Physics, 2017 We study a quantum Szilard engine that is not powered by heat drawn from a thermal reservoir, but rather by projective measurements. The engine is constituted of a system ${ \mathcal S }$ , a weight ${ \mathcal W }$ , and a Maxwell demon ${ \mathcal D }$

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 ...

Rapid optimal work extraction from a quantum-dot information engine [PDF]
Physical Review ResearchThe conversion of thermal energy into work is usually more efficient in the slow-driving regime, where the power output is vanishingly small. Efficient work extraction for fast-driving protocols remains an outstanding challenge at the nanoscale, where ...

Quantum szilard engines and breakdown of adiabaticity [PDF]
, 2018 Recent advances in experimental control over mesoscopic systems through optical trapping techniques have led to a renewed theoretical interest in the study of thermodynamic properties at small scales (Takahiro Sagawa and Sano, 2010) (Martínez et al ...
