Think of it like this: imagine you have a secret message written on a piece of paper, and you also have some additional information written on a separate piece of paper. By carefully combining these two pieces of information, you can create a new, more robust way of sending the secret message that is less affected by outside interference or noise.
Not sure I've ever read a more useless "simplification" in my life.
Imagine ~~an etch-a-sketch~~ a Magna Doodle where you have the front side of the board and someone else has the back side. Every cell must be either black or white, and a cell in one state on your board must always be in the other state on the other board. Whatever you write on your side appears in the negative on the other. It's like that, but quantum.
A but more detailed lower:
The process works as follows: the sender subjects their photon to controlled dephasing, which cancels out the initial correlations. They then perform a joint measurement on their part of the entangled pair and the qubit to be teleported. This measurement not only entangles the sender’s qubits but also remotely transforms the hybrid entanglement into local qubit-environment entanglement on the receiver’s side. Finally, the receiver applies a specific operation based on the sender’s measurement result and subjects their photon to dephasing, which remarkably converts the qubit-environment entanglement into the desired quantum state.

Pffftttt! This is just a bigger fax-machine..
Smaller fax-machine*
Anyone remember fax-bombing from the 80's?
Imagine having Piers Morgan or James Corden or Nick Griffin being teleported into your lab repeatedly, fuck thaaaaaaat.

Lol love that thumbnail
Going to need a little more than "near-flawless" before I step near one of those pads. Also, don't come at me with "it's safer than driving"... If I have a crash I just have to reassemble my limbs, not my entire atomic structure.
There's zero chance this will be used to transport matter in our lifetimes, much less sending sentient beings across space. Right now, it's just information, which is phenomenal by itself.
I know, I was being sort of glib ... But the internet doesn't get sarcasm or gentle irony.
I got you, I just think there's a lot of pop science reporting on this, and people act like we're going to have transporters. Even the thumbnail for this article implies it. The problem with that sort of hyperbolic reporting is that then people are disappointed when reality doesn't live up to the hype.
This is really big news and a great leap forward in research physics. If we can utilize quantum entanglement, it will change the world in ways we cannot even comprehend.
It would be like when Bell first called Watson, every newspaper started promising same-day Amazon delivery.
Y'know, I think I read this same hyperbolic reporting in the 80s in a New Scientist, and again in the 90s. For some reason teleportation went quiet in the early 2000's as far as popular reporting went, but it looks like it is back.
I have a suspicion that, alongside space travel, there is this fascination in getting out of this place because we've fucked it up.
I'm deeply skeptical that they even managed to transmit information ftl, since that violates a fundamental law of physics.
They transferred the qubits but using it (and knowing when you can use it) still requires non causality breaking methods.
Things like this are more useful for secure transfer of data without eavesdropping. You send qubits of data at a set time, etc and then send a message at non FTL speeds to say “it’s ready… read it” and they can do so.
Oh man, this is going to be exciting for you then. Quantum mechanics is breaking all sorts of laws of physics that were previously assumed to be inviolable.
Healthy skepticism is good, but the more you read about this, the crazier it gets. Quantum entanglement requires an entirely new understanding of dimensional spacetime.
