That still won't give us faster than light speed communication.




How do you reconcile your claim of FTL transmission with this statement directly from your link: "It is not possible, however, to use this effect to transmit classical information at faster-than-light speeds"?


The speed of transmission of Quantum entanglement would, I believe, be limited by the speed of light between the two points in space, without having to traverse a path that follows the curve of the surface of the earth.

So, communicating from Australia to Norway would traverse the diameter of the earth, rather than half of the circumference (plus satellites of course)


I don't think that it can be used to transmit information at all, but rather to establish a shared state. The key is that you can't influence the state in a way that transmits information.

It's like sharing the same random oracle, you could use it to encrypt stuff, but sharing the same random bits with another party doesn't actually let you send information

What if the "no-cloning theorem"[0] wasn't actually right? That would enable doing a bunch of copies of the same particle state, making it possible to predict the probability distribution of each particle. That way it would be possible to send information doing measurements[1] rather than forcing a particle state.

So, quantum mechanics isn't linear in nature any more? And it gets to transmit information superluminally? It's probably more likely that we're all living in a simulation and the devs accept a pull request from us increasing the speed of light so we can play games better. The no-cloning theorem itself is actually pretty fundamental to quantum mechanics and it would be very unexpected if it was wrong.
