I know there are a lot of similar question but I don't believe this to be a copy. I understand that if two people lived far away they could not transfer information through quantum entangled particles because forcing a particle into a particular spin breaks the entanglement and simply observing the particle to collapse the other part of the pair will give a perfectly random result. But what about using entanglement to sort of indirectly coordinate plans from far away:
I know this is wrong somehow and uses a childish interpretation of the idea of communicating information but this is just to make this as clear as possible: lets say the year is 3050, there are 2 leaders of an allied war who want to attack a planet, they are currently on opposite sides of the planet and have 2 plans they can decide upon, 1) both attack from the east and west at once or north and south at the same time. Using an atomic clock the leaders coordinate to check the state of quantum entangled particles (or a qubit, doesn't matter) at 12pm. If the qubit collapses as a (1/0) they go with plan A while (0/1) means plan B.
I believe that this does not constitute faster than light communication because both plans were conceived ahead of time and the particle or quantum state was just used as a random number generator, but it still seems as though the plan of attack was being transferred.
My questions are:
- could this scheme actually be used or is there something I'm missing.
- Why does this not constitute faster than light communication?
- I would also just like to hear people who are smarter than me's thoughts on the physics around this hypothetical.
