    "abstract": "It is shown that the entanglement-structure of 3- and 4-qubit states can be\ncharacterized by optimized operators of the Mermin-Klyshko type. It is possible\nto discriminate between pure 2-qubit entanglements and higher entanglements. A\ncomparison with a global entanglement measure and the i-concurrence is made.",
