Quantum Nondemolition Measurement Enables Macroscopic
... Macrorealism assumes noninvasive measurements, with the consequence that correlations, e.g., C13 ¼ hQ1 Q3 i, are equal, independently of which sequence was performed to obtain them. S1 and S3 , which differ by the presence or absence of Q2 , give the same C13 in macrorealism but not in quantum mecha ...

Measuring the quantum mechanical wave function
... classical statistics. For example, if you sum over Nn /M, or integrate over w (x) 2 , you must get unity. In light of this, it is probably more clear to say that you have `inferred’ or `determined’ w (x) 2 rather than `measured’ it, since a single observation of a particle tells virtually nothing ab ...
