Hi,

Up until the photon hits one of the detectors no indication of the way it took can be known == there is no violation of the complementarity principal since there is no simultaneity of the two natures of light (ondular and corpuscular).

Dear Faical, he put a barrier at the minimum zones of the interference and still he got same intensity. Therefore, it is not that the probability of the photon at the minima is low or zero. The photon dodged those zones! In this sense, this contradict Copenhagen interpretation based on probabilities.

On another sack, this is equivalent to the weak measurement results. Which was predicted by Bohm mechanics. However, hidden variables theories are not true. Do you see the contradiction? weak interaction results are predicted with Bohm mechanics but Aspect experiment ruled out Bohm!

That is the standard answer! One single photon goes through both slits. It is completely non local because it is in two physical places at the same time. Still it show us a wave behavior. Please, check the weak measurement experiment. In both experiments the non-local photon dogged the minima places. This means that the probability interpretation is not adequate. The probability to hit a minimum is low because the photon avoid those places whatsoever! In turns, avoiding the minima means a particle intrinsic mechanism...The photon tells its own wavelength. This sound obvious. However, nobody knows why or how the particle photon produce an electromagnetic wave...

Dear Faical, your answer and everybody in the field answer presume that the photon occupies just one physical place. This is even against what the experimental evidence shows. You would not need superluminal communication if the two entangled particle are in both physical places. This is because one is with witnessing the other at all times and places.
