Reply to comment by Adeldor in Do you think we will ever be able to communicate faster than the speed of light using entangled particles? by DefenderOfTheButter

I do understand this a bit different and would expect that this would be actually possible. According to the relativity theory the point is that the "spooky entaglement" happens at identical times everywhere.

Maybe this paper is better:

or this

"teleportation" is in my understanding "timeless" as it happens between entagled entities.

While the teleportation is instantaneous, I don't think there's any way to bypass the need for ancilla to be transported "classically," which are required for the Bell measurements at the receiver.

And there's still the causality problem (manifest here as "information causality" - PDF). Of course, one should never say never, but it seems there's always a fundamental roadblock when it comes to FTL, regardless of the path taken.

I prefer hope and dreams that if you get a little foot in the door of physics you may bust it open some day. No argument from me that there is a long way to go and propably regulariy in the wrong direction. I am however also sure that we have enough glimpses seen that einstein is not the last of it.
