Quantum dots get some electricity and then generate light in the SMALLEST possible way known to science: one stinkin' photon. This means (as I grasp the article) that the light cannot be intercepted. So the only thing that can "see" the light is the intended recipient and there is thus no other way to crack the code.
I'm certain there are flaws in the analysis, but that's still pretty fucking cool science.
