Quantum ‘yin-yang’ shows two photons being entangled in real-time::The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers.
that’s fucking beautiful, I don’t get it, but damn, that sounds and looks incredibly impressive.
I mean, it’s a Yin-Yang symbol. That’s some spooky coincidence right there. That, or someone in Asia once had a very weird dream/drug trip like when DNA was discovered to be a double-helix.
The symbol was induced by using a pump in that shape. The yin-yang arrangement is not chance, but rather man-made.
Ah. Okay, that ruins the coolness but if that’s the case I’m not going to try and bet on a dead horse.
I dunno. We can manipulate entangled electrons to look like a yin yang symbol and that’s not cool?
Edit; photons. My bad.
Photons. Not trying to be pedantic… it’s just a massive difference.
Excellent point. My apologies.
Np. Electron entanglement would be like a whole other can of insane worms that I couldn’t even begin to understand haha.
Looks cool but the spirituality grifters shoving “quantum” in the middle of their bulshit are going to go wild with this.
Their word salad can’t get wilder, they prey on the lack of skeptism.
Have you tried quantum skepticism? It’s better as it removes the negatively charged and toxic ions.
Shut up and take my money!
Fucking hell man you’re way too good at that.
edit: cancel that. i’m an idiot
How does it look exactly like the Yin Yang symbol ☯️? That’s a human construct as far as I’m aware.
They Introduced this symbol into the “pump beam” used in order to illustrate this technique’s ability to resolve images.
It’s quite simple really—the ascended masters operate on both the micro and macro levels of existence. /s
Shit, it’s the “is anything real” guy. Party’s over, go home.
Tone is difficult to convey on the internet without sounding incredibly unnatural, I took it to mean “how did they do that” instead of what I assume you read as “this is fake”.
Yeh, fair
This is a garbage article. They are claiming this is an image of two entangled photons. That’s absolute nonsense. I don’t WTF this experiment is, but it certainly isn’t a photo of photons.
did you read it?
this is a collection of a lot of images
Yes, I read it, then I read the article they sourced, and then I read the paper itself.
And what did you find?
I found Jesus.
This is also the basics of quantum communications.
Not really. In order to find the wave function you need to measure both particles and compare both sets of superposition info to know that the particles were entangled. The information sharing between Alice and Bob would still have to be through standard means.
It would be, except it’s apparently been calculated that quantum entanglement doesn’t work that way.
No spooky action at a distance
More like “no measurement without action” and “action = modification” but I get the reference, yes.
Sadly, IIRC, measuring an entangled particle on one end changes the result on that end, despite the other end trying to be the one that changes it.

I don’t think there’s really any “changing” going on. The state of both entangled particles are unknown until one is measured, but I highly doubt that the act of measuring one suddenly determines the other’s state. They were already in those states, but before measurement it was an unknown variable which could be treated as a superposition. Once one is measured, then you know the state of the other entangled particle. Not because the act of measuring one affects the other (see: spooky action), but simply because the nature of entangled particles means the other would have to have to be the opposite of what you measured.
There’s no remote interaction, it’s simply mutual information
At least, that’s my take
Edit: this is why we can’t use entanglement for FTL communication. It just doesn’t work like that
Edit 2: seems my understanding was way off, but I’m leaving this comment up for the sake of context for the replies… Thanks to the people that responded for trying to clear things up. Quantum physics is weird.
Meh, it’s a losing battle try to establish what’s actually going on mechanically. It’s best to just stick to the rules we can prove and leave the underlying “how” as an implementation detail.
What we know is that it is possible for distant particles to become entangled without respect for relativistic limits. There’s effectively no difference between saying that the entanglement propagates regardless of distance (simultaneously FTL) or that the entanglement propagates regardless of time (sub-FTL regardless of simultaneity).
The issue is that an observer must at some point have observed both particles to know that they’ve become entangled. This is already a problem at any scale, but it gets much worse at relativistic distances because you can no longer even be certain when the two tangles are entangled, including and up to whether or not the particle you are locally observing is currently entangled. You’re stuck playing relativistic Two Generals’ Problem in such a way that if there was an FTL transmission, any useful information from it is rendered inaccessible without first receiving additional sub-FTL information.
This is the fundamentally frustrating thing about quantum mechanics. As far as we currently understand physics, any experiment which would reveal the actual underlying physical nature of the quantum world would itself be physically impossible (e.g.: FTL travel, time travel, violating the uncertainty principle).
This is a common misunderstanding due to trying to think of things classically. I’d recommend “the road to reality” by Penrose if you want a better understanding.
Also it is not why we cannot use entanglement for FTL info, but you’ll understand that more once you understand entanglement better.
Just started reading this and it feels WAAAY over my head but I’m going to take author’s word for it that I will glean something from it.
Ah yeah kinda, The two particles would be in a super position state. Meaning that there could be a number of possible states and each state has a certain probability.
The reason quantum entanglement is so weird, Is that by measuring one Particle changes the state of the other particle, it is in fact spooky action at a distance. How these particles communicate with each other is unknown but we cannot use it as a communication method because the act of measuring one of the particles destroys the entanglement. The states of the particles are random before we measure it. There is no state at which both particles agree upon before they’re separated.
When the two particles are entangled, no “information” is communicated. So we can think of it as The particles exchanging random information that has no use to anything. This solves the faster than light communication problem because no real information is sent, Only random data. They’re experiments that try to test this hypothesis called the quantum eraser.
