If a quantum communiqué has changes in the slightest, it’s a telltale sign that the line has been tapped and someone who shouldn’t be is listening in. In other words, the delicate nature of a qubit allows it to act as a highly sensitive and sophisticated detector of security breaches.
That’s almost comical in a sense. At this point it seems like every U.S. communiqué would come back as “tapped”. Then again, I don’t think the NSA would be able to actually get any of the information with this level of technology — so suck on that NSA.
