The discussion emphasizes the advantages of teaching the Positive Operator-Valued Measure (POVM) concept in quantum theory to beginners, arguing it is more intuitive and simpler than introducing Born's rule. The approach suggested involves starting with qubits and using classical light polarization to motivate the concept of measurement. The derivation of the POVM from basic principles, such as the detector response principle, is highlighted as straightforward and provides a solid foundation for understanding quantum measurements. The conversation also touches on the necessity of introducing infinite-dimensional Hilbert spaces for more complex systems, such as the anharmonic oscillator, and the importance of relating quantum mechanics to classical mechanics. Overall, the POVM framework is presented as a more accessible entry point into quantum theory for students.
