Quantum Cryptography Is Said To Be "Unbreakable"

There are many security systems out there. Many have claimed to be unbreakable, until one day they are broken. Now a new network has entered the scene that claims to be unbreakable. It's called quantum cryptography.  

This system works off of the Heisenberg Uncertainty Principle. This principle means that when someone tries to view information on a network encrypted by this system, the act of viewing disturbs the network, causing it to change and therefore makes such intrusions obvious. Hence the "unbreakable" claims.

I'm not certain on the science here, but it has something to do with the photons becoming erratic, which makes the line shut down and redirect to another one, without disturbing the flow of information. Confused yet? I sure am. But it sounds cool to me!
