Is it possible to use entanglement for communication? I could be incorrect, but I vaguely recall reading that researchers were pursuing it a while ago. Even if it's just information, being able to communicate faster than light would be neat and have some big implications. But in the article, it sounds like it's not instantaneous.. so if it's faster than light, but not instantaneous, that sounds like some kind of new speed limit?
- czzr 5y agoIt’s not possible to use entanglement to send information faster than the speed of light.
- krastanov 5y agoYou can use entanglement for communication, as long as you also use some classical communication channel in addition to it. If you just want to transfer bits, entanglement does not provide much more than classical communication channels (maybe a bit better signal to noise ratio when used together). Quantum teleportation requires both entanglement and classical communication channels to be present. And all of this has nothing to do with FTL communication. No matter what piece of known physics you use, FTL communication is simply not possible. It is not just "not known how to do it", rather it contradicts and causes unresolvable paradoxes in an enormous body of extremely well verified laws of nature.
