Terabit Internet Possible Using Twisted Light?

Two anti-correlated particles are ejected from the same source.
Their quantum states are not defined (until measured) but we know that they are anti-correlated... (easiest to think of this in term of spin: one up, one down).

Assuming those two anti-correlated particles are ejected in opposite directions, they still travel at a maximum speed of c.

So, t time later, they are 2tc apart.
If you then make a measurement on one particle, you define its quantum state (let's say it's spin up)
The entangled, anti-correlated, particle must have the opposite state (spin down).

Therefore, you now have knowledge of the state of the anti-correlated particle instantly (regardless of the distance: 2tc)... but the information (that is, the entangled state(s)) has still be transmitted at c from its point of origin... it just so happens that the information wasn't defined at that time.

This is a fuzzy concept, I know.
For good explorations on it, read up on the work of David Bohm.

Thanks I'll do that :)

You need a little "learning" it seems :

The act of measurement is a reception of data , if data can be encoded , traditionally such as a 1 or 0 during each recording of the pairing value (which in this case would be spin) then you could in theory do this and transmit information across infinite distances in real time.

We've already achieved Quantum data transmission and this :

Only a matter of time now.

No, you're still wrong. The collapse of the wave form is random, so you can never use this to send 'net' information. I love it when people talk out of their ass so confidently about things they really know nothing about. The phrase "just enough information to be dangerous" comes to mind.

Outside of your condescending retort , what I was referring to is the effort to find a way to predict the outcome of the observation which is currently not possible with the classical system of thought. This is entirely theoretical at this current time , perhaps it was premature to claim a flat out "yes" and at the time I might have been thinking of Quantum Teleportation which is different animal altogether. However acting as if you understand the true nature of the collapse when the waveform is observed is equally condescending on its own.

There is no reason for disparaging tone in the matter when its a debate of current scientific and technological limitations.
 
This would be a more accurate form of what I was attempting to infer :

“In the past we have built networks that can communicate quantum information, but convert it into classical form at the network switching points. [The researchers] report preliminary experiments towards forming a network in which the information remains in quantum form.”
