    "abstract": "We present entanglement witness operators for detecting genuine multipartite\nentanglement. These witnesses are robust against noise and require only two\nlocal measurement settings when used in an experiment, independent from the\nnumber of qubits. This allows detection of entanglement for an increasing\nnumber of parties without a corresponding increase in effort. The witnesses\npresented detect states close to GHZ, cluster and graph states. Connections to\nBell inequalities are also discussed.",
