Author(s): Paolo Abiuso, Julian Fischer, and Miguel Navascués Attempts to understand multipartite quantum nonlocality are thwarted by the difficulty of devising quantum Bell inequalities (QBI) for systems composed of more than a few separate parties. In this Letter, we introduce the notion of tight connectors , a class of tensors which, if contracted according … [Phys. Rev. Lett. 137, 050204] Published Wed Jul 29, 2026
