Let me point out a different risk of providing a too detailed description of how the aliens learned about it: The risk of unnecessarily contradicting established science, and thus losing exactly those who would otherwise be most likely to enjoy detailed descriptions. In this particular case, it is clear to me (a physicist working in quantum physics) that your knowledge in this area is based basically on popular science articles (which, I regret, are often terribly misleading). If you just say they detect it through some quantum gravitational effect unknown to us, that's enough for me to keep suspension of disbelief (we don't have a successful theory of quantum gravity yet). Or some post-quantum effect. Or basically, anything we don't yet know. But if you try to explain it through entanglement, without invoking something we don't know yet, for me that breaks suspension of disbelief the same way it does if you claim in a Hard Science Fiction story that a Ford model T can go to space if you just select the right gear and then turn on the lights.
