报告简介:
　　Bell's inequalities can be seen as a family of entanglement witnesses, with a very special property: they detect entanglement without need of prior knowledge on the nature of the system or the measurements. For this reason, they can be used for ``device-independent" assessment.
In this talk, I shall review the main results in device-independent quantum cryptography, randomness generation and assessment of the quality of a source of entangled pairs (a.k.a. self-testing). Then I shall present in some detail our most recent results on device-independent certification of entangled measurements. I shall also exorcise the new buzzword "free will" by putting it in an operational context and stress the challenges related to the detection loophole.

　　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.
