I know there's a flaw here as superluminal communicaton is impossible. I was considering this scenario: As with the initial stage of the delayed time quantum eraser experiment, put two light sources through a beta barium borate chrystal creating two pairs of entanged photons. Send one pair to station on Mars and the other to a ground station. Now I gather that the way the photon is observed will force its entagled partner on the other side to behave like a particle or a wave. So what's preventing instantaneous communication. You could easily send morse code by changing the way you observe the photon, so turning on/off an interference pattern at the other side. What am I missing?
