# Information-thermodynamics link revisited

@article{Alicki2019InformationthermodynamicsLR, title={Information-thermodynamics link revisited}, author={Robert Alicki and Michał Horodecki}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2019}, volume={52} }

The so-called information-thermodynamics link created by a thought experiment of Szilard became a core of modern orthodoxy in the field of quantum information and resources theory in quantum thermodynamics. We recall existing objections against standard interpretation of Szilard engine operation and illustrate them by two quantum models: a particle in a box with time-dependent thin potential barrier and the spin-boson model. The consequences of the emerging superselection rules for…

A quantum Szilard engine considering quantum size effects and sees that insertion of the partition does not localize the particle to one side, instead creating a superposition state of the particle being in both sides, shows the validity of Landauer’s principle even in quantum SzILard engines without Maxwell's demon.
