Quantum Entanglement FTL Communication
Cluster focuses on debunking the misconception that quantum entanglement enables faster-than-light information transfer, repeatedly citing the no-communication theorem and explaining why classical channels are still required.

Entanglement doesn't mean information actually travels from point A to point B. Imagine it like tearing paper into 2 pieces without looking at it. Then both pieces are taken away. And then you look at the exact shape of the cut - and you know that the other piece of paper mirrors it exactly. There was no actual travel of information, you had it the whole time - you just looked at it when it was convenient. Quantum entanglement is nicer than that because it can also guarantee single usage (o
no, there's a theorem that states you cannot use quantum entanglement for communication: http://en.wikipedia.org/wiki/No-communication_theorem
Entanglement doesn't allow communication.
Quantum entanglement does not allow you to communicate information faster than c (though it does allow you to correlate behavior, in a way which the benefits of which can't be seen until after a light-speed delay)
No, quantum entanglement does not allow Information to travel faster than light. Classic channel is needed to know what if any unitary transformations are needed. Otherwise requiring roll of massively many sided dice. Check out No Communication Theorem.
As I understand it, you can't actually use this to transmit information. If you entangle two particles, and then send one away, and attempt to measure the appropriate property (I think it's spin), hurray: you know that the other particle's spin is the opposite.But that's not communication. It's like slicing a coin down the middle without looking at it, hiding each half in a box, and giving one of the boxes to someone going to the moon. A week later, you both open your
No, while entanglement acts instantaneously across a large distance, there's no way for that "signal" to carry any information. In order to complete the teleportation the two parties must somehow communicate in order to convey an additional piece of information. This communication would be classical and slower than light.
Nope, it’s a common misunderstanding. While the particles are entangled regardless of distance and the action is instantaneous (at least, that’s one way of interpreting it) there’s no way to actually transmit information.You may try to come up with clever encodings for electron spins, but you’ll see that you end up having to know a priory what the other end had. It’s a long topic to discuss on a HN thread but a quick YouTube search will get you interesting videos.
As far as we know, information cannot be transmitted faster than light, even between two entangled quantum particles.https://www.forbes.com/sites/chadorzel/2016/05/04/the-real-r...
As far as anyone can tell you can't use it transmit information. Their states are mirrored but you can't modify the state of on of the pairs to change the state of the other, that just breaks the entanglement. So all you really have are two particles that happen to be in the same random state at any given time.I don't think you can even tell given only one of the particles in a pair if it is still entangled so you couldn't even destructively send small amounts of informati
