Bell diagonal states with maximal abelian symmetry
Published 2 Nov 2010 in quant-ph | (1011.0515v1)
Abstract: We provide a simple class of 2-qudit states for which one is able to formulate necessary and sufficient conditions for separability. As a byproduct we generalize well known construction provided by Horodecki et al. for d=3. It is hoped that these states with known separability/entanglement properties may be used to test various notions in entanglement theory.
