Bound entanglement in the magic simplex of two--qutrits
arXiv:0804.1525 · doi:10.1103/PhysRevA.78.014303
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.
