The discussion centers on teaching the concept of Positive Operator-Valued Measures (POVMs) in quantum theory to beginners. It emphasizes that introducing POVMs is simpler than explaining Born's rule, particularly when starting with qubit states and classical light polarization. The proposed teaching approach includes using the detector response principle (DRP) to derive measurement postulates and employing quantum detection tomography for practical applications. This method provides a more intuitive understanding of quantum measurements compared to traditional methods.
PREREQUISITESStudents and educators in quantum physics, particularly those interested in teaching measurement concepts and quantum theory fundamentals. This discussion is beneficial for anyone looking to simplify complex quantum mechanics topics for beginners.
Yes, this is the book I had quoted from. There is also another, quite recent book with two authors the same:vanhees71 said:Seems to be a great book! I've even (legal) access to it, though it's published in 1995. Is this the book you have in mind? At least it's about the right topic and also discusses the SGE in some detail.

With ''generalization of the formalism'' he means the POVM formalism generalizing the traditional textbook formalism which only features projective measurements.Willem de Muynck said:The examples discussed in sections 7.2 through 7.5 show that a generalization of the formalism is necessary for describing even the most common methods of quantum mechanical measurement, like the detection of photons using a detector that is not 100% efficient. This also holds true for such experiments as the double slit experiment, being a paradigm of standard quantum mechanics. It will not be surprising, then, that an analysis of this experiment based on the standard formalism can hardly be a reliable one, and that conclusions based on such an analysis should be considered with some reservation.
