Addendum to "Sufficient conditions for three-particle entanglement and their tests in recent experiments"
Geza Toth, Otfried Guehne, Michael Seevinck +1
A recent paper [M. Seevinck and J. Uffink, Phys. Rev. A 65, 012107 (2002)] presented a bound for the three-qubit Mermin inequality such that the violation of this bound indicates g…
Multipartite entanglement in spin chains
Otfried Guehne, Geza Toth, Hans J. Briegel
We investigate the presence of multipartite entanglement in macroscopic spin chains. We discuss the Heisenberg and the XY model and derive bounds on the internal energy for systems…
Entanglement Detection in the Stabilizer Formalism
Geza Toth, Otfried Guehne
We investigate how stabilizer theory can be used for constructing sufficient conditions for entanglement. First, we show how entanglement witnesses can be derived for a given state…
Two measurement settings can suffice to verify multipartite entanglement
Geza Toth, Otfried Guehne
We present entanglement witnesses for detecting genuine multi-qubit entanglement. Our constructions are robust against noise and require only two local measurement settings, indepe…
