I'm not asking about two way or even repeating communication. Is it possible to entangle particles, keep then entangled and send half of them far away, and delay their choice for an arbitrary amount of time? What I'm thinking about is asking a yes or no question: Is there life on Planet X? So I take half the particles and trap them in an entangled state on the probe which goes off at subliminal speeds. When the probe reaches its target, it does its analysis and comes up with a binary answer. From that it either gives the particles one or two slits to finally be released through. Back on earth at the same time, the other half of the particles are released and either form an interference pattern or clump based on the behavior of the particles light years away?
