Abstract
Testing quantum mechanics against alternative theories must be done in a way that does not make assumptions about the validity of any particular theory, in particular, without presuming the correctness of quantum theory. Here, the authors set bounds on possible deviations from quantum theory using the formalism of Generalized Probabilistic Theories by experimentally probing a three-level system consisting of a photon shared among three modes. They find no evidence for the breakdown of quantum theory.
