Entanglement and permutational symmetry
Geza Toth, Otfried Gühne
We study the separability of permutationally symmetric quantum states. We show that for bipartite symmetric systems most of the relevant entanglement criteria coincide. However, we…

Entanglement detection
Otfried Gühne, Geza Toth
How can one prove that a given state is entangled? In this paper we review different methods that have been proposed for entanglement detection. We first explain the basic elements…

Spin squeezing and entanglement
Geza Toth, Christian Knapp, Otfried Gühne +1
What is the relation between spin squeezing and entanglement? To clarify this, we derive the full set of generalized spin squeezing inequalities for the detection of entanglement.…
