I know this has been asked many times, but I have a hard time "crystallising" it in my mind.
First: lets say we teleport a DVD (with quantum teleportation), isn't this Ftl communication ?
Second: would it be possible to create 2 quantum computers fully entangled ?
If we assume that it would be possible, having them in separate locations, then "asking" the first one a question to which we already know the answer, then observe that answer, would the answer appear on the second computer, would it be Ftl communication ?
Now I know someone will say "but the one with the second computer has no way to know if it the first one has already been "observed", to wich I'll respond : but if we do systematic observation on the computer, like every x time, so that each one of them is always in sync about readings.
Thanks in advance !
