NIST says it’s made Unbreakable Encryption

“Unbreakable” encryption works in real time over long distances, NIST says – Scientific Blogging

In the internet age, when 120,000,000 smart people on Digg can see an article about your technology, it takes some real courage to use the term “unbreakable”, but the guys at NIST are doing just that. They say they have built a prototype high-speed quantum key distribution (QKD) system that can perform a theoretically unbreakable “one-time pad” encryption, transmission and decryption of a video signal in real-time over a distance of at least 10 kilometers.

Here’s my question if it’s “Unbreakable” and it’s decrypted at the other end, eventually it will not be unbreakable if mass used.
