Progress on the Kretschmann-Schlingemann-Werner Conjecture
Frederik vom Ende
Given any pair of quantum channels such that at least one of them has Kraus rank one, as well as any respective Stinespring isometries , we prove that there exis…
Finite-Dimensional Stinespring Curves Can Approximate Any Dynamics
Frederik vom Ende
We generalize a recent result stating that all analytic quantum dynamics can be represented exactly as the reduction of unitary dynamics generated by a time-dependent Hamiltonian.…
Reachability in Infinite Dimensional Unital Open Quantum Systems with Switchable GKS-Lindblad Generators
Frederik vom Ende, Gunther Dirr, Michael Keyl +1
In quantum systems theory one of the fundamental problems boils down to: given an initial state, which final states can be reached by the dynamic system in question. Here we consid…
Phase Spaces, Parity Operators, and the Born-Jordan Distribution
Bálint Koczor, Frederik vom Ende, Maurice de Gosson +2
Phase spaces as given by the Wigner distribution function provide a natural description of infinite-dimensional quantum systems. They are an important tool in quantum optics and ha…
