Entanglement and non-locality of four-qubit connected hypergraph states
We study entanglement and non-locality of connected four-qubit hypergraph
states. One obtains the SLOCC classification from the known LU-orbits. We then
consider Mermin's polynomials and show that all four-qubit hypergraph states
exhibit non-local behavior. Finally, we implement some of the corresponding
inequalities on the IBM Quantum Experience.
