A counterexample to a conjectured entanglement inequality
R. F. Werner, K. G. H. Vollbrecht
We give an explicit counterexample to an entanglement inequality suggested in a recent paper [quant-ph/0005126] by Benatti and Narnhofer. The inequality would have had far-reaching…

Separability properties of tripartite states with UxUxU-symmetry
T. Eggeling, R. F. Werner
We study separability properties in a 5-dimensional set of states of quantum systems composed of three subsystems of equal but arbitrary finite Hilbert space dimension. These are t…
