It's quantum mechanics, not relativity, after all. And no one has said anything (so far) about modulating the entangled effects to produce useful signals. An FTL signal is a direct violation of relativity, but that's not necessarily the case for FTL effects.

It should be noted that Philip Ball appears to contradict everything I've just written.

'It should allow the arrangement of one set of quantum particles to reproduce more or less instantly that of a similar collection of distant particles. In this way a message encoded in photons of light could be transmitted from one place to another without sending the photons across the intervening space.'

I take 'more or less instantly' to mean 'not instantaneously.' Ball also seems to think a message could be sent using this method.

Maybe because it's quantum mechanics people are having trouble stating clearly just what occurred in the experiment. And what they expect to result from it.

I have been reading about the military's use of quantum keys to encode messages sent from the ground up to satellites in orbit and vice versa. However instantaneous the relationship between the keys held by the sender and the receiver, the message itself must still be comprised of photons which travel the intervening distance at c. No violation of either relativity or causality.

Maybe Ball slipped a little when he wrote that paragraph? Wouldn't be the first time more has been read into quantum teleportation than is really there.
