Tnx, I think I get it know. For the case I describe Bob wil always get a singles count of 50*0,5 + 50*0,5 =50. Alice wil get 85*0,5 + 15*0,5 = also 50. Now it makes sense to me.
Many thanks for your answer.
If I understand your answer correctly, after the beam splitter, the entangled photons are randomly polarized in a superposition of two ( perpendicular ) states? Or there is no polarization, only superposition with the same response to each angle, meaning 50%.
So...
I am wondering what happens in the case of 100 entangled photons with a polarization angle of 0 degrees (or 0 and 90) that interact with Alice at 22,5 degrees and Bob at 45 degrees in a Bell Experiment.
Do I get a count of 85 for Alice and 50 for Bob, which means a maximum coincidence count...
