Study shows quantum communications across interstellar space could be possible

Not only is there a potential for us to use quantum communications to send messages across interstellar space, it may also serve as a way for aliens to communicate with us as well.

The concept of life existing elsewhere in the galaxy is fascinating, as is the ongoing, rapid advancement of technology here on planet Earth. Combining the two, it sounds like we may have a promising way to communicate across interstellar space via quantum communications.

As reported by, a team of scientists at the University of Edinburgh’s School of Physics and Astronomy “has used mathematical calculations to show that quantum communications across interstellar space should be possible.”

The possibility, as outlined in a paper published to the journal Physical Review D, notes the potential to use quantum communications to open a dialogue with extraterrestrial beings. Not only that, but also the possibility of those same beings using quantum communications to communicate with us as well.

Not only is quantum communications a way for us to send messages, the scientists also remarked that optical and microwave bands could work equally well. Furthermore, it’s suggested that quantum teleportation across interstellar space should also be possible.

All in all, the news is exciting, and we look forward to learning more as the matter continues to be studied. Whether our communications can be picked up, or whether we’re able to pick up chatter from elsewhere, it sounds like these developments in quantum communication may be able to bring us one step closer to verifying the existence of life elsewhere in the galaxy.

      Fire up the Ansible, we've got dirty Formics to kill.

        I am pleased this was the first reply :)

      Yuuup. We are such infants when it comes to physics, especially the quantum realm. So much more is possible than we could even begin to understand. I'd bet everything on it.

      Don’t you first need something on the other end for that to work? Like you’d need a quantum computer say here and one there and then they can communicate because they will know Evers being said.

      I don’t see how extraterrestrials would do that unless they happened to have a quantum device if their own in the right spots looking for our communication and they be able to understand what it even means.

        I look forward to the Earth-Moon, Earth-Mars, and Moon-Mars ansible relays.

      I don't understand. Is this saying you can transmit information with quantum entanglement faster than light? Or is it just saying that there's enough empty space that non-FTL communication can span incredible distances and still be readable?

        Later: Over the past several years, scientists have been investigating the possibility of using quantum communications as a highly secure form of message transmission. Prior research has shown that it would be nearly impossible to intercept such messages without detection. In this new effort, the researchers wondered if similar types of communications might be possible across interstellar space.

          That's what I thought, which seems much less consequential for both attempting communication with other species or communicating with our own across vast distances.

            I’m not sure why we’d use this over radio waves which are the speed of light and the data in it can be encrypted.

              With quantum encryption any attempt to read the message whip its being sent would cue the receiver in that its been attempted to be observed. Since the act of observing the message changes it.

                yeah but in the case of 'broadcast in case any aliens can hear us' wouldn't we explicitly not want that property?

      This is a bit over my head but I think it's cool that Shacknews is putting out articles like this

      Morse code using mechanical watch hands seems crude though.
