Gaussian and Qubit Semigroup Dynamics beyond GKSL
Nadine Diesel, Charlotte Bäcker, Walter T. Strunz
A well established approach to describe open quantum system dynamics is the celebrated Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) master equation. In this article we aim to shed…
How rare are Markovian quantum dynamics?
Charlotte Bäcker, Nick Maryshchak, Walter T. Strunz
A profound understanding of decoherence and dissipation in quantum dynamics is crucial for the realistic modeling of the evolution of quantum systems. In open quantum dynamics one…
Quantum memory precludes mixed-unitary dynamics
Charlotte Bäcker, Konstantin Beyer, Walter T. Strunz
Unital quantum channels, defined by their property of leaving the maximally mixed state invariant, form an important class of quantum operations. A distinguished subset of these ch…
Verifying Quantum Memory in the Dynamics of Spin Boson Models
Charlotte Bäcker, Valentin Link, Walter T. Strunz
We investigate the nature of memory effects in the non-Markovian dynamics of spin boson models. Local quantum memory criteria can be used to indicate that the reduced dynamics of a…
Entropic witness for quantum memory in open system dynamics
Charlotte Bäcker, Konstantin Beyer, Walter T. Strunz
The dynamics of open quantum system are often modeled by non-Markovian processes that account for memory effects arising from interactions with the environment. It is well-known th…
