It's just true that it can't be eavesdropped on. It's actually easier to eavesdrop on fiber traffic because the exposed fibers can simply be bent at the right angle to let enough of the light out to determine the data. It can't be changed that way though.

*not true* it's not true...
Ok...
Good luck sending a message thats "not" tampered with.
Crossing through all that traffic its bound to run into a hitch.
No one will be able to vote because the machines won't accept a message that isn't being solicited.
Little explanation
It can be eavesdropped on. *But* physics say the photons will be affected so the other end will know there's someone in the middle... or the fiber is broken. That data is just discarded for use as a key for encryption. Let's remember this is not quantum encryption but Quantum Key Distribution.
The great limitation of this technology is distance, only 30 Km.
