Abstract

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.
