Quantum Eraser / Home Version

    Hello,
    some time ago I had a little idea which was posted here:
    http://asterisk.apod.com/viewtopic.php?f=39&t=21247
    (see the last post)
    Maybe some minds about such possibility to explain the phenomenon?

    What do you mean by "double polarization"? If light passes a diagonal polarizer it will be polarized diagonally. There is no difference between diagonal, horizontal and vertical polarization, except for orientation.

    Lets consider something like/similar to pilot wave
    http://en.wikipedia.org/wiki/Pilot_wave
    which pass both slits simultaneously and gets one of two passable double polarizations.

    I see nothing on that page that explains what you mean by "double polarizations". Looking at your eraser setup, I see no difference from the lecture setup except that you've turned all polarizers 45° and split the eraser in two parts. If you're looking for an "easy classical" explanation, a nonlocal hidden variable theory is not the way to go.

    I do not know the exact answer. But is my idea more weird than any other?
    Could we just think about an experiment which would be able to test it?

    Yes here is just turned polarizers 45°, nothing new in setup.

    Somewhere I had read that the results of this experiment
    http://www.bbc.co.uk/news/science-environment-13626587
    very well fits to pilot wave interpretation.

    But the most interesting would be to know is here some experimental possibilities to test the idea.

    What idea?

    That photon has more complex structure than it was thought before.
    That some, maybe not equivalent parts of it can pass slits simultaneously and whole
    photon's structure can enter some unknown until now state of double oscillations perpendicular to each other.
    I can not know exactly how it can work in details.
    Anyway it looks more realistic compare to interpretations like “many worlds”.

    Sorry, but your conceptual understanding of photons is lacking. Read up on classical electrodynamics and the history of quantum theory.

    I am not stating that my idea is the best. This is not my area.
    But still I know a little something about photon :smile:

    If the idea is wrong maybe could be some experimental way to prove it?

    Do someone tried to use longer waves for mentioned experiment?
    Let say 1- 10 mm.
