OK, but can you detect in the spaceship when Q2 collapses? (I know no quantum physics beyond a few articles0
If so why can't you simply modulate the signal on top of a series of collapsing entangled pairs. Basically morse code with the timing of the collapses, you don't care what value they collapse too.
No. You can ask the spaceship to measure Q2 after a certain period of time. So "fly away and at a specific time T measure Q2" would be the command. Sorry I should have made that more clear.
