Thanks John. I'm not exactly up on Quantum Communications yet.

Hi Ray--

I remember reading (very superficially) about 'action at a distance'
experiments; is there some follow through. Sorry to be so dense.

By your interpretation, there is no information transmitted faster than
But if the entanglement disentangles over FTL links, even though the
information to decode that fact travels at lightspeed, doesn't that imply a
FTL connection between the quantum particles? And if there is a FTL
connection, then I can forsee a FTL commununications link. Perhaps involving
entangled triplets, quadruplets, or something? Well, I don't mean to start a
big debate. I am out of my field. But isn't there some controversy among the
experts about this?
