Device-independent certification of multipartite entanglement using measurements performed in randomly chosen triads
Device-independent certification of multipartite entanglement using measurements performed in randomly chosen triads
We consider the problem of demonstrating non-Bell-local correlations by performing local measurements in randomly chosen triads, i.e., three mutually unbiased bases, on a multipartite Greenberger-Horne-Zeilinger state. Our main interest lies on investigating the feasibility of using these correlations to certify multipartite entanglement in a device-independent setting. In contrast to previous …
