    What is a photon in respect to electromagnetic waves?

    When discussing classical physics and waves, the single detections are caused by the limitations in the devices, so we can't assume ideal experiments. See section 2.1 in Generation of single photons and correlated photon pairs using InAs quantum dots. If what you're saying is in fact "an...

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

    Which-way double slit

    Anyone who can settle this? Looking for the accurate quantum mechanical prediction... The photon's wavefunction passes both slits, and then interferes in the center of the screen. Will the split probability waves superposition into a 100% probability of diagonal polarization, or will the...

    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...

    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.

    What is a photon in respect to electromagnetic waves?

    This would only be the case if you had a perfect source, perfect identical beamsplitters and perfect identical detectors. In reality, you do not. if you performed this experiment and both detectors were triggered simultaneously, that would not imply that light is a wave. One could simply argue...

    What is a photon in respect to electromagnetic waves?

    AFAIK, there is no effort to consolidate these two. Quantum theory came about due to the failures of classical physics to explain certain phenomena, most importantly the hydrogen spectra. The hydrogen series and Rydberg formula was discovered in the 1880s, but it wasn't until 1913 that Bohr...

    What is a photon in respect to electromagnetic waves?

    They are not the same so much as different interpretations of the same phenomenon - light. Electromagnetic waves represent the classical physics view of light, and photons are a part of quantum theory's description of light. Common mistake is to try and understand photons and EM waves as a...

    Which-way double slit

    Appreciate the comments, no need to be sorry :smile: .. Perhaps someone with better knowledge on the subject can weigh in. if the photon will have diagonal polarization, how could one detect which-way info?

    Which-way double slit

    If we add polarizers to the slits like DrChinese describes above, I believe there is a difference in predicted outcomes between quantum physics and classical physics. A difference I believe can be tested. Both quantum and classical physics predict that the interference pattern will disappear...

    Double slit experiment - QM or wave?

    All this tells me is that the detection limit is close to a 50% split, so that there is a small chance of a "non-detection" (ie exact 50/50 split). So if you remove the beamsplitter you would only get an insignificant increase in detections. Please do so, would appreciate that very much.

    Double slit experiment - QM or wave?

    My interpretation does not violate conservation of energy. There are no "new photons" as you call it. ALL light hits the detector, but if the light is interfering destructively at some point, it will not set off the detector. Instead it will continue it's propagation somewhere (not clear) and...

    Double slit experiment - QM or wave?

    The OP question was not a general one about wave-particle duality. I simply stated that QM could not fully explain the double slit with light, nothing else. That's what I was saying. Well THAT's interesting. Why don't you show me a paper with that setup. Add 4-5 levels of beamsplitters to the...

    Double slit experiment - QM or wave?

    There is a limitation on both intensity and wavelength. Since blue light is closer to the electron wavelength it would require less intensity than the IR to set off the detector. So if both setups show identical results, that tells me that the blue source emits lightwaves with lower intensity...

    Double slit experiment - QM or wave?

    Ok, I see your point now. And you are right, for some reason I was assuming that the non-slit distribution would be the equivalent of a totally constructive area. So I guess my original statement about the predictions of wave theory were incorrect. Thank you Cthugha for pointing this out so...

    Double slit experiment - QM or wave?

    I do worry. Both source and detector are imperfect, which is why I'd prefer no other manipulation between them. You asked me how a singe dot could be produced, not a single dot in an interference pattern. Ofcourse, if you add a double slit the principle would be the same, only with interference.

    Double slit experiment - QM or wave?

    How do I neglect constructive interference? define "nothing". And I'm not saying the photons will "go through" the detector. I'm not sure what happens with them, maybe they're reflected and scattered? This is the QM interpretation, yes. Any change will only redistribute the photons, so the...

    Double slit experiment - QM or wave?

    From a QM point of view there's no difference I'm sure, there's only two outcomes - detection or no detection. But if you consider a wave, the process of beamsplitting is an imperfect one, there's not just a right or left choice. With low-intensity waves resulting intensities may be considerably...

    Double slit experiment - QM or wave?

    Firing rate is the actual number of photons fired. The number you would detect if there is nothing in between the photon gun and the detector. The detection rate is the detectors count. Not true. This is what QM predicts, not wave theory. In wave theory, there are just as many photons hitting...

    Double slit experiment - QM or wave?

    2. I'm not satisfied with a reference to this experiment because it has other components that we don't share the same interpretation about. So in order for me to argue the detection rate issue, I would first have to argue the beam splitting issue for example. And I would prefer not to because...

    Double slit experiment - QM or wave?

    Which scenarios? and what about the "which-way" observation can't be resolved? Both my setup, the quote you supplied, and Cthugha's post tells you why interference is enough, and both interpretations do not result in equal observations. QM predicts no change in clicks / number of detections...

    Double slit experiment - QM or wave?

    I don't have access to the article via AJP. The Thorn paper seems to be more of a bell test setup with beam splitting and coincidence counts, i.e. no interference. So how is it relevant? Concerning duality, different experiments show different things, and one does not take precedence over...

    Double slit experiment - QM or wave?

    Oook? .. The quote you supplied completely proves my point. I don't get it. The "revival of the clicks" cannot be interpreted as anything other than elimination of destructive interference. I'm guessing this is more of a semantics issue now then. What would you say is the difference...

    Double slit experiment - QM or wave?

    I propose a setup to distinguish between the quantum interpretation and the wave interpretation of the double slit experiment. Briefly, they are: Quantum The photon gun fires a photon that travels through either slit A or slit B, then hits a detector cell registering a spot in the...
