Bell inequalities versus entanglement and mixedness for a class of two - qubit states
arXiv:quant-ph/0402112 · doi:10.1016/j.physleta.2004.06.007
Abstract
For a class of mixed two -qubit states we show that it is not possible to discriminate between states violating or non - violating Bell - CHSH inequalities, knowing only their entanglement and mixedness. For a large set of possible values of these quantities, we construct pairs of states with the same entanglement and mixedness such that one state is violating but the other is non - violating Bell - CHSH inequality.
