Abstract: We will continue our survey of the basic mathematical structure behind quantum probabilities, introducing the concept of effects, leading to a proof of a simplified version of Gleason's theorem, as presented in http://arxiv.org/abs/quant-ph/0205039 .

Abstract: Rigidity (also known as self-testing) expresses the idea that states and measurements can sometimes be deduced from their effects. I will present the mathematics behind this idea, using the magic square game (https://arxiv.org/abs/1512.02074) as an example.

Abstract: This is the second part of a two-part lecture. Rigidity (also known as self-testing) expresses the idea that states and measurements can sometimes be deduced from their effects. I will present the mathematics behind this idea, using the magic square game (https://arxiv.org/abs/1512.02074) as an example.

Abstract: We start our discussion of the "operational approach" to foundations of quantum theory as presented in Chiribella, D'Ariano, and Perinotti, http://journals.aps.org/pra/abstract/10.1103/PhysRevA.84.012311.

Abstract: I will discuss how to calculate the optimal score for two-player XOR games via arrangements of real vectors. This is a method attributed to Boris Tsirelson.

Abstract: I will discuss how unknown quantum measurements can be used to simulate partially trusted measurements. This approach, which is related to the notion of rigidity, has been useful in quantum cryptography ( https://arxiv.org/abs/1402.0489 ).
