I think you're confusing the internal correlation of the entangled pairs with the use of the entangled pair to transmit the state of a third particle, which is what quantum teleportation is. The third particle can be in any state you like and teleporting that state (which doesn't happen FTL) very much is the transfer…

No, you can't transfer information instantaneously (or any information at all) using just a shared entangled pair. You can transfer quantum information using one (that's quantum teleportation), but it also requires sending classical information, and hence has the usual speed limitations.

But what's being done is quantum teleportation, not just the creation of entangled pairs, so information is being sent (although not instantaneously of course).

Discussions of quantum teleportation bring all the ladies to the yard, and they're like, good thing it shared a bunch of entangled photons with my yard.

That's what happens with entanglement, but you can't use that to send information, because the outcome is random (you can't control what your measurement result would be). In quantum teleportation, to transfer the state, you need to communicate with the receiver.

No information is sent FTL in quantum teleportation.

Hard to speculate about these things, I wouldn't claim to have a great grip on possible applications. But in principle you could, say, use long-distance quantum teleportation to communicate quantum states between two far-apart quantum computers.

So the state being transferred isn't that of the entangled pair, they're just a tool that gets used. It's the state of some other particle (say) that you have.

It doesn't give you FTL communication. To do the teleportation you need to communicate in the usual, limited by c, way.

You have to communicate to do the teleportation, so it certainly doesn't give you FTL information transfer. It does let you send quantum states over large distances.

As per our other conversation, the information that's transferred is the quantum state of a third particle, not that of the entangled pair.

It's mentioned in para 8 of the Guardian article.

Cryptography is quite a good analogy for it (not surprising it's useful for that). If I want to safely send you a secret message I can have it conveyed by a trusted courier, which is inconvenient. But if we share a random key I can encrypt the message with that and safely send it to you over the public internet,…

The gloves aren't really entangled in the quantum sense though, they're just classically correlated - you know if you have the left, the other box has the right, because obviously it must.

The second. Quantum teleportation is the standard term for it.

It's not the instantaneous movement of matter or the instantaneous transmission of information. The teleportation requires the sender to communicate with the receiver in the usual way (phone or whatever), which is limited by light speed. It's the transfer of an arbitrary quantum state using an entangled pair the…

What you're describing is the correlation between the two halves of the entangled pair, but that's not the information that was transferred. The teleportation transfers the quantum state of a third particle, by using the entangled pair.

Not instantly (it's no faster than sending information usually is), but it can be used to send quantum information, which is generally quite difficult.

Riker sold his soul to Ardra.

It's quantum teleportation. Admittedly, for all that there's some logic to the name, it's fairly different from Star Trek teleportation, and articles about it are usually terrible at making that clear.
