Bell diagonal states with maximal Abelian symmetry
Dariusz Chruściński, Andrzej Kossakowski · Physical Review A · 2010
We provide a simple class of 2-qudit states for which one is able to formulate necessary and sufficient conditions for separability. As a by-product, we generalize the well-known construction provided by Horodecki et al. [Phys. Rev. Lett. 82, 1056 (1999)] for $d=3$. It is hoped that these states with known separability and entanglement properties may be used to test various notions in entanglement theory.
