Yes, it is entanglement.† One thing which is
surprising in entanglement is that all particles
created at the time of the Big Bang *were* entangled.
Thus the universe as a whole is one single FTL

I was aware that the there were plans for using
entanglement for simple calculations I did not know
that they had proceeded.
Regarding the teleportation approach, have a look at
D. Boschi, S. Branca, F. De Martini, L. Hardy and S.
Popescu: "Experimental Realization of Teleporting an
Unknown Pure Quantum State via Dual Classical and
submitted to Physical Review Letters, Los Alamos
preprint archive quant-ph/9710013.
Just sorry i canít give you a reference. It was on the lines of one plus
one. Not exactly a pc or a mac, but you have to start somewhere. As
Francesca has said, i will add your reading to the list that is slowly
piling up beside me. One thing i would add is that although all the
particles created at the big bang are entangled, finding the pairs could
pose a problem.
