Finite de Finetti for convex bodies and Polynomial Optimization
Julius A. Zeiss, Gereon Koßmann, René Schwonnek +1
Leveraging a recently proposed notion of relative entropy in general probabilistic theories (GPT), we prove a finite de Finetti representation theorem for general convex bodies. We…

Generalised contextuality of continuous variable quantum theory can be revealed with a single projective measurement
Pauli Jokinen, Mirjam Weilenmann, Martin Plávala +3
Generalized contextuality is a possible indicator of non-classical behaviour in quantum information theory. In finite-dimensional systems, this is justified by the fact that noncon…
