Not sure I understand your question or suggestion here, but my understanding is that space-time are not factors in quantum entanglement. Alain's classic experiment with entangled photons, for example, exhibited instantaneous response, which I believe demonstrates signal-less communication faster than light speed. My inkling is that the explanation for this phenomenon is that the universe may be holographic.
BTW, in a very recent experimentm a photon has now been successfully quantum-teleported across space-time (25km) from one crystal to another:

Actually, quantum teleportation described in the article is the same as quantum entanglement. Its also mentioned in the article. I can only imagine the technologies that will evolve from further understanding of this.
