Image constructed using quantum entanglement of photons

The image is not that of quantum entanglement of photons. Instead, the researchers used the technique of quantum entangled photons to CONSTRUCT the image.
I couldn't avoid wondering...
About about this particular one they write:
Finally, Fig. 6 demonstrates an example of the potential applications of biphoton digital holography. The unknown pump beam can carry information about an image or be scattered by a three-dimensional object. The information about the scatterer is transferred to the SPDC state and can be retrieved through our technique (Fig. 6b). We show this in the case of off-axis holography, which can present limitations for complex structures due to the limited camera resolution. These limitations are not related to our proposal and can be improved by employing other approaches, for example, on-axis phase-shifting digital holography9.
You can see other images besides this one in the paper (which is linked to at the very bottom of the article): https://www.nature.com/articles/s41566-023-01272-3
I wouldn't go so far as to say 'fabrication'.
Many people (including myself and others in this HN thread) seem to have taken the yin-yang image as literal insight into the physical structure of a photon. They could have used a different image, perhaps one of their institution's logo and avoided this misinterpretation.

It’s not their fault the world is full of people hoping to find magic when the science is more magical than where their weak imaginations led them.
> this is not an image of photon entanglement. if you read the actual paper it is explained that, in testing information reconstruction from biphoton states, the researchers encoded the Yin-Yang symbol onto the pump beam photons superimposed with reference photons. the superposition of these waveforms was then split into photon pairs which, after being separated, were sent onto a single photon sensor array.
Followed by the poster say “oh god damn”
The second link seems to redirect me to another story about fossils, so I’ll guess it was pulled?
"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
Let's please stop arguing about the image now*, and move on to more interesting points.

That's rude. Let's not confuse Hackenews with a ChatGPT prompt.
At face value your chain of logic isn't coherent, how can creator be sure he isn't just a creation? And you get to absurdities it's creators all the way down.
If literally, you have some science to contend with! :)
You can entangle 2 particles, you can entangle 3 particles, you can entangle n particles (although actually doing so becomes a quite hard engineering problem as n grows), you can even entangle different properties of the same particle with each other so the spin and position of an electron can become entangled.
Human brains love dual/pairwise properties for some reason, but they don't seem to actually come up in physics very often.
If it was just arranged like that for the fun of it then it’s a sad day that scientific journalism neglects to mention that and uses click bait tactics and ambiguity to ‘promote’ scientific discoveries.
