Two Results in the Quantum Theory of Measurements

Simone Del Vecchio, Jürg Fröhlich, Alessandro Pizzo, Alessio Ranallo

1/12/23 Published in : arXiv:2312.00599

Two theorems with applications to the quantum theory of measurements are stated and proven. The first one clarifies and amends von Neumann's Measurement Postulate used in the Copenhagen interpretation of quantum mechanics. The second one clarifies the relationship between "events'' and "measurements'' and the meaning of measurements in the ETH-Approach to quantum mechanics.
