Hello: I am curious if it could be theoretically possible to use QM as a communications device to make really long distance calls. I've been reading on locality and my understanding is just beginning so bear with me as I may have it all wrong. But on a basic level if we could affect a set of photons from a star say 1000ly away, wouldn't our intercession here show up there instantly? I sort of mixed in Einstein's concept of "particles from the same source". Could this somehow really work? Thank you.
