Seminar, Peter Love (Tufts University), Pictorial Thinking in Quantum Contextuality

Title: Pictorial Thinking in Quantum Contextuality

Abstract: Contextuality captures the ability of quantum systems to express correlations that are not accessible to physically reasonable classical hidden variable theories. Contextuality is a resource for quantum computing and an obstacle to efficient classical simulation of quantum computers. In this talk I will present a number of results concerning contextuality that use geometrical or graphical reasoning.
