    "abstract": "In this paper we describe how three qubit entanglement can be analyzed with\nlocal measurements. For this purpose we decompose entanglement witnesses into\noperators which can be measured locally. Our decompositions are optimized in\nthe number of measurement settings needed for the measurement of one witness.\nOur method allows to detect true threepartite entanglement and especially\nGHZ-states with only four measurement settings.",
