Image constructed using quantum entanglement of photons
- solraph 3y agoI was under the impression that being able to transfer information by entangled photons means that "instant" (ie; breaking light speed) communication is possible. Given the article doesn't mention this at all, what am I missing?
- badcatsociety 3y agoAnnoyingly, all we have is the word ‘constructed’ to describe the image, which could still imply there’s some natural process that reflects the Ying Yang structure. Is there anyone who knows if there’s really any connection between the Yin Yang shape and the data? Or was it just arranging the data into a fun shape with no relation to any physical properties? Does anyone here actually know? 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.
- akasakahakada 3y agoWhy is that Yin Yang symbol appears?
- Ygg2 3y agoHonestly, I think it's for funsies. Kinda like picking a fuuny acronym.
- mistermann 3y agoIt increasingly often feels to me like the creator/programmer/whatever of this simulation (or whatever it is) is feeding us novel prompts to see how we will react. :)
- Ygg2 3y agoThat's a completely mental way of interperting this post and this world. I meant the physicist are doing it for funsies not the Lord almighty. 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.
- mistermann 3y agoWhen you say "you", are you speaking literally or colloquially? If literally, you have some science to contend with! :)
- stronglikedan 3y agoIt's a visualization of the wave function, not an image of entangled photons, so it's meant to convey what the images represent in a form that's human "readable". (Think data visualizations)
- akomtu 3y agoIf quantum particles are the probability function, then the image shows the photons themselves.
- jinwoo68 3y agoIt feels so natural because yin and yang are not two separate things but two sides of the same thing, just like two entangled particles are.

- eigenket 3y agoIts worth emphasising that entanglement is not a two-party / duality specific thing. 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.
- andsoitis 3y agoIn case you're wondering whether quantum entangled photons position themselves in a Yin Yang formation, the answer is no. The image is not that of quantum entanglement of photons. Instead, the researchers used the technique of quantum entangled photons to CONSTRUCT the image.
- dang 3y agoOK, I've put image construction in the title above to try to ward off further misunderstanding. Let's please stop arguing about the image now*, and move on to more interesting points. * (I don't mean you, but the other commenters complaining about this)
- davibu 3y ago"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.
- rmbyrro 3y ago"to CONSTRUCT the image" [in a way that would generate more buzz and press?] I couldn't avoid wondering...
- andsoitis 3y agoThe paper[0] contains other images too but this one is certainly more intriguing even if it could lead people to jump to wrong conclusions. 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.

- ko27 3y agoNote that it's impossible to actually see quantum entanglement or the wave function. This demonstrates an interesting way to visualize it.
- l33tman 3y agoIf the wavefunction can be prepared in the same way multiple times you can do quantum state tomography on it to reconstruct the wavefunction, this is essentially what they do in the paper but in a more efficient way than the state of the art.
