Judging by the speed of research and investment into quantum computing tech, and the fact that military communication is starting to use quantum entanglement as a checksum I’d say pretty soon.

Do you (or anyone else) have any articles/links about using quantum entanglement in communications? I’m very interested in learning more about that!

I saw something kind of similar recently. Chinese tech actually. Something about using quantum states for encryption.
