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…
Taming multiparticle entanglement
Bastian Jungnitsch, Tobias Moroder, Otfried Gühne
We present an approach to characterize genuine multiparticle entanglement using appropriate approximations in the space of quantum states. This leads to a criterion for entanglemen…
Increasing the statistical significance of entanglement detection in experiments
Bastian Jungnitsch, Sönke Niekamp, Matthias Kleinmann +6
Entanglement is often verified by a violation of an inequality like a Bell inequality or an entanglement witness. Considerable effort has been devoted to the optimization of such i…
Magnetic response enhancement via electrically induced magnetic moments
B. Jungnitsch, J. Evers
The realization of negative refraction in atomic gases requires a strong magnetic response of the atoms. Current proposals for such systems achieve an enhancement of the magnetic r…
