Quantum entanglement communications also have fundamental problems that will likely render them effectively unusable. You need a key to decrypt anything you send, and the key has to travel no faster than c. It’s impossible to tell the data from the noise without the key. Attempting to read the data or to change the data being sent also collapses the effect, which can only be fixed by bringing the two systems together. In short, you can only send a single packet of data and you can’t use it without a key transmitted using traditional methods.
