We’re not detecting signals from aliens because, in all likelihood, everybody but the Terrans are using quantum entanglement communication for vast distances, and no one’s seriously used radio signals since the time of their great, great, great, great, great, great grandad.
- gilbetron 5y agoWhat's the benefit of using QE for communicating that would outweigh its downsides? And if you say "instantaneous communication", you might want to read more about QE :)
- NotSammyHagar 5y agoPlease explain the downsides then. Does it take too much effort do to make them work, too much energy?
- gilbetron 5y agoGetting entangled particles to both sides of the conversation, maybe there's a way to entangle particles at a distance? I believe current attempts creates entangled photons at one end and sends half of entangled pairs to the other end. Remember that once you "read" from an entangled pair, it becomes "unentangled". Plus photons like to become unentangled along the way! Literally can do the same thing with unentangled pairs with all the benefits (except one) with none of the downsides! The reason to do so (which is an awesome reason) is secure communication.
