From the responses I realize my problem is not in the relation between information and the width of a beam of light, but between information/resolution and the surface area of some holographic media. It confuses me why is lack of information evenly distributed to still contain the whole...

I guess my problem there is that I understand photography in the context where resolution is proportional to the number of photons hitting the detector, so less photons less information, but instead of missing pixels in high resolution image, we get low resolution image blurred over high...

In the process of trying to understand holography I encountered a detail that I kind of knew before, but just now I realized I have no idea how it works, how is it even possible. I’m talking about a simple pinhole camera where supposedly no matter how tiny a hole is a beam of light would still...

It's a question I had from a long time ago, so I forgot exactly where and what, but some QM descriptions seemed to imply electron would simply appear at point B, sometimes even before disappearing from point A, but in any case would appear at new position without actually traversing the distance.

Before that I would like to understand why use QM to address optical problem in the first place. I want to step back into the 19th century, there was Huygens–Fresnel principle which is supposed to explain diffraction. I would like to know why and how exactly this principle fails in any kind of...

Is there consensus on the stance of QM in regards whether motion is actually continuous or not?

I don't see a problem with HBT. I would be surprised if a single photon could split in two. It seems there is an assumption that for a photon to interfere with itself it would first need to split, but in holography interference pattern is not the result of wave interference, but wave...

I agree, and it's why 'photon' has its own page. So we ended up talking about semantics, in a way, and I don't think my questions were addressed, or at least I don't get it yet. Let me unpack and focus on the points I am asking about. Double slit - single photon experiment Mystery: why is the...

Never heard of it before. If photons do not exhibit their wave nature while propagating through space, why would you expect them to interfere like waves?

Looks like it's wide enough to go through, otherwise it would get absorbed between the slits and there wouldn't be a pattern. Isn't it the wavelength that needs to be in some special relation to the slits separation?

You do not? https://en.m.wikipedia.org/wiki/Electromagnetic_radiation In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space...

When it lands, when it gets absorbed, yes. But until then, and at the time it's passing the slits, it's suposed to still be a 'radiation', a wave, not a photon yet. Right?

There was a problem with explaining the double slit experiment even before single photon were used, some explanations claimed it has something do with observation or measurement and such. I don't consider wave-particle duality to be the problem here. The problem with the single photon double...

Sure, I'm just pointing to general situation in the field.

What equation makes us think "single photon" equals only one wave? Why wouldn't a single wave interfere with itself like waves usually do? What mystery are you referring to? In holography everything seems to work just perfectly, slits or no slits.
