Does Quantum probability collapse imply FTL information travel ?

Yes.

What's more, such information can travel backwards in time.

But it's not the kind of information we can use to send ordinary messages or signals.

See link on quantum teleportation. In particular, it notes that it cannot be used for superluminal communication. However, that does not mean that quantum bits or quantum information can't be sent non-locally. See 2nd link about that.

Edit: It should be pointed out that FTL quantum information doesn't violate relativity. As a matter of fact, Quantum Field Theory incorporates both. If virtual particles can travel backwards in time, so can quantum information. Furthermore, deBroglie matter waves behave just like tachyons, travelling at c²/v speed, which is always FTL.

Still furthermore, the Wheeler-Feymann emitter-absorber theory strongly suggests backwards quantum causality, but papers have been written in an effort to remove this seemingly unlikely scenario. See 3rd link. Also, see 4th link about quantum retrocausality. Experiments are underway in an effort to demonstrate true retrocausality. Anyone want to place bets? The jury is still out.

No. What information could you encode? Do not know where a given photon will impact. All you know is the probability that it will hit at a given location. When it hits there, that is all you know.

Wave-Particle is not the only Interpretation of QM. There are over 20 Interpretations. Most do NOT involve waves.

Let's back up just little to a concept. Some quantum mechanics theorists do not accept Wave-Particle Interpretation of quantum mechanics. They argue that a quantum has never been observed as a wave. But, by weird quirk of science, the equations of wave mechanics do describe the Probability of finding a quantum at a given location. So the wave equations are not describing a wave but the probability of finding a quantum. That is called the "Probability Wave Interpretation."

So, let's look at the 2-Slit Experiment using the Probability Wave Interpretation. We run the 2-Slit with a very dim light source so that we get one photon at a time going through the slits and the Photoelectric Effect to map where the photons hit the screen. We get particle behavior, each photon hits at a single location on the screen. Over time we find that different photons hit different locations on the screen. The wave equations predict where the photons will hit and sure enough the photons hit ONLY in the locations the wave equations predict and never in the locations the wave equations predict no impacts. Over time and billions of photons, the interference pattern builds up one dot at a time. You can open and close the slits as you wish and get the exact impact locations the wave equations predict.

No.

There are unresolved problems with quantum mechanics.

FTL travel may never be not possible for many reasons

Here are two things that should have been resolved:

1. They still do not understand the physicsal basis of QM.

2. They have not unified QM with relativity correctly notwithstanding

the fine work of Dirac and those who followed him.

Nature trumps mathematics. I predict, without proof,

that neutrinos, information, binary ones and zeros transmitted

via spin entanglement for example, or whatever will not

be found traveling faster than the speed of light. While the spin wave

of one particle may interfere with another some finite distance away in

a clear experimental way, said action and thus the transmission of bits

(large amounts of information) will not occur FTL even though they may

find anomalies when dealing with small numbers of "bits".

I use Photon and it works fine. I got it here http://bit.ly/1k3F20z
