You can't use quantum entanglement to send messages instantly. Thus, there is no such technology.
The nature of entanglement experiments is as follows.
You have a central source of two particles in an entangled state. One particle goes left, the other right. When you detect one at detector A, and the other at detector B, then you will find that the result at this detector and that detector are correlated. And you will find that the correlation is not compatible with causal-deterministic parameters. This is Bell's theorem.
But notice that it does not say you can determine some message and send it. Consider.
Suppose you are here with detector A, and your compatriot is on some distant planet with detector B. And suppose we even have some pre-arranged source of entangled particles, such that if detector A sees a spin up, detector B must see a spin down, and the reverse at both also.
There is still no way to send a message. If your friend sits at B and carefully observes particles, he won't be able to discern from what he sees anything about any message you want to send. If you get an up he must get a down. But you cannot predict what you will get from the entangled pair. If you want to send "up up up down" to indicate 1110, you can't. Because the next thing you detect is equally likely to be up or down.
So you will get a random stream of up-down values. And he will get the corresponding stream of exactly opposite values. But there is no message here.
The thing that $seems$ to go instantly is the correlation. If you get a down, he must have an up. But you can't tell that until you compare the results. Your friend cannot even tell, from $only$ his stream of measurements, whether your detector is even working. Or whether it still exists.
Try it this way. Imagine that between the two planets there was a random source of red and blue light flashes. Even supposing you can tell the flashes apart, so that you know when you see "red red red blue" that so did your friend. You can't control when the flashes are red or blue. So you can't sit at your detector and say "I want to send red red red blue to indicate 1110" because your friend can't tell, from the flashes alone, which sequence is your message. And you can't choose what the next flash will be, so you may see an arbitrarily long sequence of flashes that does not correspond to 1110. You can't use this to send a message.
