That actually makes sense. Had you heard of this "entanglement" theory before?
The way I see it is that the computers communicate with each other that doesnt allow others to join in the "channel" because it can only communicate with the other channel and by the time something like brute force would have figured out the encryption the "channel" will be closed or changed. They say they are using photons (light) to transfer data. How does one hack light with out powerful/costly recievers.
And I think I just confuised myself.
