Bell inequalities classifying biseparable three-qubit states
2006
Physical Review A. Atomic, Molecular, and Optical Physics
We present a set of Bell inequalities that gives rise to a finer classification of the entanglement for tripartite systems. These inequalities distinguish three possible bi-separable entanglements for three-qubit states. The three Bell operators we employed constitute an external sphere of the separable cube.
