Simple experimental generation of a four-photon cluster state and distinguishing classes of genuine four-qubit entanglement using witness operators
We experimentally demonstrate a simple scheme for generating a four-photon cluster state. We show that the produced state has genuine four-qubit entanglement which is discriminated from a class including GHZ and W types of entanglement.
