Can Longer Waves Enhance the Quantum Eraser Effect at Home?

Click For Summary

Discussion Overview

The discussion revolves around the potential enhancement of the quantum eraser effect using longer wavelengths, with participants exploring various interpretations of polarization and the nature of photons. The scope includes theoretical considerations, experimental possibilities, and conceptual clarifications related to quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Experimental/applied

Main Points Raised

  • Some participants question the concept of "double polarization" and seek clarification on its meaning in the context of light passing through diagonal polarizers.
  • One participant suggests a pilot wave model to explain how light might pass through slits simultaneously, proposing that photons could have a more complex structure than traditionally thought.
  • Another participant challenges the validity of the proposed experimental setup, noting similarities to existing lecture setups and expressing skepticism about the use of nonlocal hidden variable theories for classical explanations.
  • There is a suggestion to consider whether longer wavelengths, specifically in the range of 1-10 mm, could be utilized in the quantum eraser experiment.
  • Some participants express uncertainty about the originality and feasibility of the proposed ideas, questioning whether they are more unusual than other interpretations.
  • One participant emphasizes the need for a deeper understanding of classical electrodynamics and quantum theory to support their claims about photons.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interpretation of "double polarization" or the validity of the proposed experimental ideas. Multiple competing views remain regarding the nature of photons and the appropriateness of the experimental setup.

Contextual Notes

Limitations include a lack of clarity on the assumptions behind the proposed ideas, the dependence on specific definitions of polarization, and unresolved questions about the experimental design and its implications.

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?

After quantum pass the wire with diagonal polarizers it gets double
polarizations
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?
 
Hydr0matic said:
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.
