So quantum entanglement acts faster than light but it's not technically communication and not actually transferring "information"?
Can someone explain this to me?

I'd suggest a forum search. It's been explained here dozens of times.Chrisjohnson said:So quantum entanglement acts faster than light but it's not technically communication and not actually transferring "information"?

quantum mechanics exhibits what one might not have realized beforehand was even a logical possibility: it doesn’t allow communication faster than light, but simulating the predictions of quantum mechanics in a classical universe would require faster-than-light communication.
Strilanc said:No. You can't use it for communication.
You are missing the point. The spin is whatever it is when you measure it, not something you can set it to be. It is random. What is not random is that whatever it is when you measure it, the other particle will be the opposite. You have NO way of knowing whether the other person has already measure the other particle unless that information is communicated sub-FTL.Chrisjohnson said:I thought if we could spin it then we could maybe do something like Morse code. Based on what that guy said

Yes, if you could control whether you got spin up or down, then it would be possible. But changing it AFTER measurement would not allow such communication.Chrisjohnson said:Well it was just a hypothetical. "IF" we COULD change the spin, then we could use it, correct?
Just wondering. Idk why people are being so condescending.
"Communication" normally means some sense of "the transmission of something meaningful". In that sense, there is no information transmitted. There is simply a situation where you have what amounts to being two halves of a single construct that is such that when you know something about one half, you automatically know something about the other half, but that does not "communicate" anything meaningful between the two halves. You can verify after the fact of measuring one that measuring the other gave the expected result, but since you already knew that, it doesn't tell you anything.Chrisjohnson said:I didn't get an answer, more or less a confirmation on that "it's not classical communication but there is some sort of "communication" between the two particles."
You know, Not in the literal sense, but like cause and effect. 1 affects the other.
Right? I'm noob

Entanglement is a phenomenon in quantum mechanics where two particles become correlated in such a way that the state of one particle affects the state of the other, regardless of the distance between them. This correlation is often referred to as "spooky action at a distance" and has been proposed as a potential mechanism for faster than light communication as the change in one particle's state would be instantaneous, no matter how far apart they are.
No, currently, there is no scientific evidence to support the idea that entanglement can be used for faster than light communication. While entanglement has been observed and studied extensively, it has not been shown to be a reliable means of communication.
If it were possible, faster than light communication would challenge our current understanding of physics and have significant implications for communication, technology, and our understanding of the universe. It could potentially allow for instantaneous communication across vast distances, revolutionizing the way we communicate and share information.
While there have been some experiments and studies looking at the potential for using entanglement for communication, there is no current research or experiments that have successfully demonstrated faster than light communication via entanglement. Further research and experimentation is needed to fully understand the potential of entanglement for communication.
One major limitation is the fact that entanglement is a purely quantum phenomenon and cannot be observed or utilized at the macroscopic level. This means that any potential communication using entanglement would be limited to the quantum realm, making it difficult to apply in practical scenarios. Additionally, the reliability and security of such a communication method would need to be thoroughly studied and understood before it could be used in any real-world applications.
