Well we don't know that yet.. But it might be possible with corelating (Entageld) Atoms.. but the problem is still that u have too travel there first.... So that would still maybe bring a No too your answer!

In the Enterprise thread I remember hearing that communication through quantum entanglement would be instanteneous.

how do you teleport things? use a rocket. then throw nukes out the back and detonate them. sure it will take a while to get there, but after that, information exchange will be instant.

 

I believe they teleported an atom a few weeks back.Im not saying we can teleport things now I was asking if it would work.

Given that the original post asked that if you could send a message a distance of 1 light year in less than a year. This method is quite useless because you basically need some sort of an arrangement at the destination and you can't just send a message and automatically recieve it.

What?

Are you saying the quantum entanglement won't work or will work? If you got there, yes, information exchange is instantaneous, no matter the distance.

Yes. You just have to modify the spin of the atoms, and the corresponding one light years away will change instantaneously. You just monitor the spin of the atoms, taking a change one direction to be 0, another 1.

 

It's considerably more complicated than that. You can't "monitor" the spin without affecting the outcome. If the spins of the the atoms that Alice and Bob have are entangled, and Alice knows the spin of A, then Bob's spin will have a definite value. But what happens if Bob measures first? Then the A spin will be set by the measurement of B. AFAIK, once you make the measurement, the entanglement is done. You aren't changing the spin to send information, you are encoding the spin.
