Multiparticle entanglement in graph-diagonal states: Necessary and sufficient conditions for four qubits
Otfried Gühne, Bastian Jungnitsch, Tobias Moroder +1
The characterization of genuine multiparticle entanglement is important for entanglement theory as well as experimental studies related to quantum information theory. Here, we comp…

Entanglement Witnesses for Graph States: General Theory and Examples
Bastian Jungnitsch, Tobias Moroder, Otfried Gühne
We present a general theory for the construction of witnesses that detect genuine multipartite entanglement in graph states. First, we present explicit witnesses for all graph stat…
