Entanglement in quantum hypergraph states — •Jan Nöller1 and Mariami Gachechiladze2 — 1Technische Universität Darmstadt — 2Technische Universität Darmstadt
Hypergraph states are the natural generalization of well-known graph states, capturing multipartite entanglement between three or more parties.
We investigate how local Pauli stabilizers of symmetric hypergraph states can be used to quantify their geometric entanglement measures, and to explain exponentially increasing violation of local realism.
Specifically, we recover some known results for states with low hyperedge cardinalities and extend these further to infinitely many classes of hypergraph states.
Finally, we derive some results on robustness for the violation of separability inequalities against particle loss.
