    Regrettably, this just doesn't fly.  Quantum measurments can't
transfer real information faster than the speed of light.
Quantum mechanics (or rather quantum field theory) is consistent
with (special) relativity.  "There ain't no free lunch!"

Since this is very far a normal comp.arch topic, I've pointed follow-ups
to sci.physics.
