ok, does this also mean that communication is free from restraints that particles suffer.. as in would this allow faster than light communication?
i understand that solely utilising quantum entanglement, a ftl phenomenon, one is unable to communicate classical information but does this method utilise the zeno effect to afford this communication by controlling when to cease and reinstate the systems evolution?
two parties with entangled particles within quantum systems agree on a baud rate and the transmitter alters the systems evolution until it takes on a desirable state then arrest the evolution until the next scheduled modulation, then evolve the state to the next desired expression, wait for the next modulation, and on and on
effectively the information transfer would adhere to causality, the observer would be subject to the baud rate, but the distance traveled between the parties could be greater than one that light could travel within that baud rate
Er. Quantum entanglement is not a faster than light phenomenon. Or, at least, describing it as such is rather pointless. It's no more 'faster than light' than 'realizing something about a faraway place' is.
Isn't collapse of the probability wave instantaneous across the arbitrary distance between entangled particles, from the frame of the measurement, in violation of relativity, and isn't that what Einstein disliked?
The wave function isn't really this thing that physically exists but is really a data structure which exists only in your head that captures the information you have about a quantum system. So yeah collapse is instantaneous, but that's just because you can update something in your head instantly because you learned something about something that happened far away.
I don't know that that's true. I'm by no means, even remotely, an expert. But it sounds like you've got a "hidden variables" take on it; that you're suggesting the probability wave is our statistical prediction of a systems state limited by our ignorance, which is what Einstein believed, and has been since contradicted by physical experiment showing violation of Bell's inequality? Am I mistaken? Feel free to correct me.
Ah that's not what I'm saying but it's subtle. Access to hidden variables, if they existed, would allow you to predict a measurement outcome. I'm not saying that. I'm saying the wave function is a tool that allows you to write down all the correlations. In other words, the wave function is a tool that allows you to reproduce all the probability distributions
It has to have been possible for the information to have traveled between the parties normally. In this case, it has to have been possible that a photon would have traveled between the two. Since the information couldn't have arrived FTL normally due to the everyday causality problems, it also couldn't have passed through this channel FTL.
