Communication through entanglement still requires transmitting all the information you are trying to communicate through a physical communication channel like radio or some other channel like lasers or whathaveyou. The only supposed “benefit” of the communication is that it prevents undetected eavesdropping. Although, that’s hardly even a great benefit, because you want to prevent eavesdropping, not just detect it, because that means the presence of an eavesdropper would kill all communication. There is thus not even a practical security benefit for communication through entanglement. It’s largely overhyped. May have some niche use cases but not anything revolutionary.
