    "abstract": "We introduce a general method for the experimental detection of entanglement\nby performing only few local measurements, assuming some prior knowledge of the\ndensity matrix. The idea is based on the minimal decomposition of witness\noperators into a pseudo-mixture of local operators. We discuss an\nexperimentally relevant case of two qubits, and show an example how bound\nentanglement can be detected with few local measurements.",
