Journal ArticleDOI
Thermodynamics of information
TL;DR: In this article, the authors present a theoretical framework for the thermodynamics of information based on stochastic thermodynamics and fluctuation theorems, review some recent experimental results, and present an overview of the state of the art in the field.
Journal ArticleDOI
Experimental demonstration of information-to-energy conversion and validation of the generalized Jarzynski equality
TL;DR: In this paper, the authors demonstrate the information-to-energy conversion by feedback control has been demonstrated experimentally and demonstrate that feedback can enable the transformation of information into energy without violating the second law of thermodynamics.
Journal ArticleDOI
Generalized Jarzynski equality under nonequilibrium feedback control.
Takahiro Sagawa,Masahito Ueda +1 more
TL;DR: The Jarzynski equality is generalized to situations in which nonequilibrium systems are subject to a feedback control, and an "information ratchet" is introduced, which can transport a Brownian particle in one direction and extract positive work from the particle.
Journal ArticleDOI
Minimal energy cost for thermodynamic information processing: measurement and information erasure.
Takahiro Sagawa,Masahito Ueda +1 more
TL;DR: The fundamental lower bounds on the thermodynamic energy cost of measurement and information erasure are determined and constitute the second law of "information thermodynamics," in which information content and thermodynamic variables are treated on an equal footing.
Journal ArticleDOI
Second law of thermodynamics with discrete quantum feedback control.
Takahiro Sagawa,Masahito Ueda +1 more
TL;DR: A new thermodynamic inequality is derived which leads to the maximum work that can be extracted from multi-heat-baths with the assistance of discrete quantum feedback control, and this maximum work can exceed that in conventional thermodynamics.
