Optimizing a quantum reservoir computer for time series prediction
Aki Kutvonen, Takahiro Sagawa, Keisuke Fujii
Quantum computing and neural networks show great promise for the future of information processing. In this paper we study a quantum reservoir computer (QRC), a framework harnessing…
Quantum jump model for a system with a finite-size environment
Samu Suomela, Aki Kutvonen, Tapio Ala-Nissila
Measuring the thermodynamic properties of open quantum systems poses a major challenge. A calorimetric detection has been proposed as a feasible experimental scheme to measure work…
Thermodynamics of information exchange between two coupled quantum dots
Aki Kutvonen, Takahiro Sagawa, Tapio Ala-Nissilä
We propose a setup based on two coupled quantum dots where thermodynamics of a measurement can be quantitatively characterized. The information obtained in the measurement can be u…
Thermodynamics and efficiency of an autonomous on-chip Maxwell's demon
Aki Kutvonen, Jonne Koski, Tapio Ala-Nissilä
In his famous letter in 1870, Maxwell describes how Joule's law can be violated "only by the intelligent action of a mere guiding agent", later coined as Maxwell's demon by Lord Ke…
On-chip Maxwell's demon as an information-powered refrigerator
J. V. Koski, A. Kutvonen, I. M. Khaymovich +2
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 ba…
Entropy production in a non-Markovian environment
Aki Kutvonen, Tapio Ala-Nissilä, Jukka P. Pekola
Stochastic thermodynamics and the associated fluctuation relations provide the means to extend the fundamental laws of thermodynamics to small scales and systems out of equilibrium…
Influence of nanoparticle size, loading, and shape on the mechanical properties of polymer nanocomposites
Aki Kutvonen, Giulia Rossi, Sakari R. Puisto +2
We study the influence of spherical, triangular, and rod-like nanoparticles on the mechanical properties of a polymer nanocomposite (PNC), via coarse-grained molecular dynamics sim…
Dissipated work and fluctuation relations for non-equilibrium single-electron transitions
J. P. Pekola, A. Kutvonen, T. Ala-Nissila
We discuss a simple but experimentally realistic model system, a single-electron box (SEB), where common fluctuation relations can be tested for driven electronic transitions. We s…
