Weak measurement and the measurement problem

[QUOTE="Killtech, post: 6545868, member: 439294"] I think I figured out how to correct my setup to make sense in terms of my question. Initially I mistook a superposition for an ensemble which made me look for a different initial state. Because if the initial state is entangled in the way vanhees wrote, the HOM interference will just yield an coincidence distribution uniform in the polarization angle - so no interference at all. However, as it is a superposition state, then in theory the probing photon can be produced to be in the identical state, too (i.e. it needs to be similarly entangled). Now indeed the HOM interference should reappear, albeit I won't have useful parameters to play with for the probing photon. Therefore the setup now becomes only a check for the persistence of entanglement. The general idea is to try to isolate the aspect/information that is affected by measurement in theory and also take advantage of the theory describing that aspect/information to takes part in interactions, therefore using an interaction as an sensor for that change. My thought was that in probability theory and the theory of stochastic processes you can classify information whether it interacts by its the time evolution of its probability being non linear. That means it cannot be though as independent of the described system and is therefore an irreducible aspect of the real state of the system, which in principle by that nature can be measured at least indirectly.
