Bound entanglement in the set of Bell-state mixtures of two qutrits
Reinhold A. Bertlmann, Philipp Krammer · Physical Review A · 2008
We investigate the entanglement properties of a three-parameter family of states that are part of the magic simplex of two qutrits, which is a simplex of states that are mixtures of maximally entangled two-qutrit Bell states. Using entanglement witnesses, we reveal large regions of bound entangled and separable states.
