Entanglement or separability: The choice of how to factorize the algebra of a density matrix
Walter Thirring, Reinhold A. Bertlmann, Philipp Köhler +1
We discuss the concept of how entanglement changes with respect to different factorizations of the total algebra which describes the quantum states. Depending on the considered fac…
Asymptotic Entanglement and Lindblad Dynamics: a Perturbative Approach
Fabio Benatti, Adam Nagy, Heide Narnhofer
We consider an open bipartite quantum system with dissipative Lindblad type dynamics. In order to study the entanglement of the stationary states, we develop a perturbative approac…
The structures of state space concerning Quantum Dynamical Semigroups
Bernhard Baumgartner, Heide Narnhofer
Each semigroup describing the time evolution of an open quantum system on a finite dimensional Hilbert space is related to a special structure of this space. It is shown how the sp…
