00:00Imagine you hold a laser pointer, which is invisible to any adversary, but you see it
00:27because you know where you need to point, and you're measuring how you're pointing.
00:33So you know you're pointing it very precisely to the other party you want to communicate with,
00:38and that information cannot be monitored, cannot be intercepted, and cannot be jammed
00:44because also the receiver itself is designed in a way that it also has a very narrow acceptance angle.
