WebFeb 15, 2024 · I think that 1. and 2. are not the core of the problem; 3. is a technical assumption, and some strengthening of Gleason's theorem could allow a weaker assumption (but this is a math problem); 4. can be thought as an experimental assumption (these probabilities can be given as limits of experimental frequencies) or an ontological … In mathematical physics, Gleason's theorem shows that the rule one uses to calculate probabilities in quantum physics, the Born rule, can be derived from the usual mathematical representation of measurements in quantum physics together with the assumption of non-contextuality. Andrew … See more Conceptual background In quantum mechanics, each physical system is associated with a Hilbert space. For the purposes of this overview, the Hilbert space is assumed to be finite-dimensional. In the … See more Gleason's theorem highlights a number of fundamental issues in quantum measurement theory. As Fuchs argues, the theorem "is an … See more In 1932, John von Neumann also managed to derive the Born rule in his textbook Mathematische Grundlagen der Quantenmechanik [Mathematical … See more Gleason originally proved the theorem assuming that the measurements applied to the system are of the von Neumann type, i.e., that each possible measurement corresponds to an orthonormal basis of the Hilbert space. Later, Busch and independently See more

Then μ extends to a bounded linear functional φ on B ( H). Having these two theorems in mind I would like to ask the following: iris hyperemia
