You can't actually send information faster than light though. http://en.wikipedia.org/wiki/Faster_than_light_travel#Quantum_mechanics http://en.wikipedia.org/wiki/Faster_than_light_travel#Quantu... "Certain phenomena in quantum mechanics, such as quantum entanglement, appear to transmit information faster than light. According to the No-communication theorem these phenomena do not allow true communication; they only let two observers in different locations see the same event simultaneously, without any way of controlling what either sees."

let two observers in different locations see the same event simultaneously [...] So ... what if observer B does nothing while observer A (a long, long ways distant) measures something. Can B then "see" the corresponding wave function collapse, thereby knowing that A took a measurement? What I'm working towards here is not caring about the measurement outcome, but rather knowing that a measurement took place, and using that as "information". If you have enough entangled quanta don't you then have a primitive serial line? It should be obvious here that I'm not very familiar with QM. Just wondering.
