Is it true information can travel faster than light through quantum connectivity?

Answer 1

What I've heard of this is that particles can become entangled. I was trying to explain it, but I don't know enough about it. So I would advise you to search: quantum entanglement. This should give you some info on the phenomenon that gives rise to the possibility you are asking about.

Hope this helps.

Answer 2

Not quite, but it's a common misconception. Scientists have shown that particles can be linked to have opposite spin properties, so that a change in one particle results in an instantaneous change in the other particle. This phenomenon is called quantum entanglement, but it does not enable faster-than-light computing. The problem is that information about these particles still must be transmitted through a conventional communication channel. What quantum entanglement does make possible is quantum computing, where a single electron can encore more than a single bit of data, because its spin properties are used for data, not just its presence or absence. So the computing power is exponentially higher, even though data still must travel at or below the speed of light.

Answer 3

Referring to ohick078's answer, yes, quantum entanglement between two particles can be established, and technically no matter how far away you take the two particles, once you "collapse" the state of one, the other will collapse instantaneously, to the opposite state (if particle A is 1, particle B becomes 0, and vice versa, for example).

I think recently the idea of instantaneous communication was ruled out though, because someone showed that is impossible to CHOOSE one state for the first particle that you collapse: you can knock over the domino, but you can't choose which way it falls. So you can't transmit information by this route. You can't even send information by timing when you collapse the first particle, because then you'd have to check the second particle - and any checking causes it's state to collapse as well, and since no information can be obtained from the second particle's state, no information can be transmitted. It's a fascinating way in which something seems to happen at a speed faster than light, but doesn't: nothing we do can lead us to observe a faster than light effect, but the theory says, in a way, that faster-than-light effects occur. It's kind of like something that happens underneath the normal operation of the universe, which doesn't violate any rules on the surface.

I agree that to learn more about this, search "quantum entanglement", and also "spooky action at a distance", which is the (poor) translation from German of what Einstein called this kind of effect.

Answer 4

This is an area of active research in modern physics. The idea is called quantum entanglement and I have to admit I don't know that much about it but it is related to the Pauli exclusion principle. Remember how you could put two electrons into one orbital of an atom by giving them opposite spin? But you couldn't have two electrons with the same spin in the same orbital because they would be occupying the same state (the quantum equivalent of space, like two people can't sit in the same chair). Quantum entanglement is essentially done by coupling two particles such that one particles state has to be the opposite of the other in order to maintain the validity of the exclusion principle. By measuring one particle you can set its state and in turn the other particles state. This does not depend on the distance between them and hence one is in some sense sending information over a non-zero distance instantaneously. That is the theory, not sure how well it works though (I heard a guy get ripped into at a seminar where he presented this theory).

Answer 5

According to special theory of relativity, neither energy-matter nor information can travel at a speed higher thant that of light. Even if EPR paradox occurs in quantum physics (entanglement), most physicists agree on that it does not permit to tranmit information at a speed higher than c.

The way people get around the idea that entanglement implies instantaneous communication is that no actual information is passed when the entangled particles affect each other. The arguement is as follows (using a non-QM example):

Say you agree to send out two beams of light to your two friends who live on opposite sides of the galaxy (you live in the middle). Ahead of time you tell them that if one of the beams of light is red the other will be blue. So you send the blue beam to your friend on one side and immediately she knows that your other friend is recieving a red beam at the same time. Aha! You say, my friends have now communicated at a speed faster than the speed of light and violated relativity, but no real information has been passed between them. You have told both of them at a normal sub-luminal speed about what you just did and that's all. (A way of proving there's no faster than light communication is that you could lie and send them both the same coloured beam of light and they would never know!).

Answer 6

No, not information. Quantum connectivity, or quantum entanglement, refers to the phenomenon whereby two objects in related quantum states maintain their relative states even if separated. Imagine you have the two electrons in a normal helium atom. You know that one must be spin up, and one must be spin down. You strip them off the atom in such a way as to preserve their relative state. You know that if you look at either one, you automatically know what state the other is in. Now you take one electron, without looking at it, and go somewhere far away, while your partner stays with the other one. Once you get to your new location, you look at your electron and see its spin state. Instantaneously, you know the state of the one your partner has. If spin up is 1 and spin down is 0, you just instantaneouls sent a piece of binary code! The problem is, there's no way to know what piece of information you sent - up or down, 0 or 1 - prior to sending it. So there's no actual information sent.

Answer 7

This is a strange situation. Certain particles have been shown to have opposite spins to their counterpart. If one of the particles spin changes, then so does the other. But how does the other particle know to change its spin??? No one knows. This is the question. Even if the particles are light years away from each other, as soon as one of them changes spin from negative to positive, the other one instantaneously changes from positive to negative. VERY INTERESTING!!!

no because nothing travels faster then lite lite travels 186,000miles per second.

Answer 10

No, it is definitely not true.

No experiment has ever been done that shows this, and it is theoretically impossible.
