Thermodynamic length for far from equilibrium quantum systems
Sebastian Deffner, Eric Lutz
We consider a closed quantum system, initially at thermal equilibrium, driven by arbitrary external parameters. We derive a lower bound on the entropy production which we express i…

Holevo's bound from a general quantum fluctuation theorem
Dvir Kafri, Sebastian Deffner
We give a novel derivation of Holevo's bound using an important result from nonequilibrium statistical physics, the fluctuation theorem. To do so we develop a general formalism of…

Generalized Clausius inequality for nonequilibrium quantum processes
Sebastian Deffner, Eric Lutz
We show that the nonequilibrium entropy production for a driven quantum system is larger than the Bures length, the geometric distance between its actual state and the correspondin…
