　　It is known that the physical principle of "no-signaling" alone does not single out quantum correlations, and that the post-quantum no-signaling correlations share many of the features that are supposed to define quantum physics (intrinsic randomness, no-cloning, violation of Bell's inequalities...). This talk focuses on the principle ofInformation Causality (IC), which generalizes no-signaling and has been proved to come close to singling out quantum correlations. I shall review the successes of IC and also the difficulties that the subsequent research is meeting. In particular, I shall emphasize how a generalization of the initial bipartite scenario to a multipartite one is a most urgent necessary step.

　　Prof. Valerio Scarani directs a productive research group in Quantum information science. His current research is focused on quantum key distribution, quantum cryptography, device-independent tasks and fundamental theory in quantum information. Recently, his group made excellent contributions in Reference-frame independent protocol, Device-independent state estimation, Finite-key security bounds,Device-independent security bound against collective attack, Notion and first examples of dimension witnesses and Reviews of both achievements and challenges.
