Operational work fluctuation theorem for open quantum systems
Konstantin Beyer, Walter T. Strunz
The classical Jarzynski equality establishes an exact relation between the stochastic work performed on a system driven out of thermal equilibrium and the free energy difference in…
Regularization of Riemannian optimization: Application to process tomography and quantum machine learning
Felix Soest, Konstantin Beyer, Walter T. Strunz
Gradient descent algorithms on Riemannian manifolds have recently been proposed as a practical tool for optimizing quantum channels. We add rank-penalizing regularization terms to…
Dynamics of a strongly coupled quantum heat engine -- computing bath observables from the hierarchy of pure states
Valentin Boettcher, Richard Hartmann, Konstantin Beyer +1
We present a fully quantum dynamical treatment of a quantum heat engine and its baths based on the Hierarchy of Pure States (HOPS), an exact and general method for open quantum sys…
