There are probably as many notions of non-classicality as there are people who will attend this talk (or read this post). In quantum information, we are in the privileged position (or not, according to taste) of having, in recent years, developed some pretty formal mathematical frameworks for what we mean by non-classicality.

In this talk I will present some of these, how they are used to prove quantum behaviour, how this can translate to quantum advantage for certain information processing tasks in networks, and their fragility and what we can try to do about it.
