Unbreakable Encryption for Optical Cable Data?

The new Quantum Broadband Network is so secure, it's unbreakable. So far. By relying on the laws of quantum mechanics as a security mechanism, Toshiba researchers have created a theoretically hack-proof speed data link. But is this new high-speed network connection really impossible to hack? And how does it work? The technology involves the sender embedding a "key" within the message. The receiving party is only allowed access to this data, and if a third party tries to mess with the quantum key, the key will be altered, signaling a hack, and remain encrypted. What makes this technology so breakthrough? "It was Toshiba's development of a photon detector that can actually pick up individual photons at the hard-to-detect wavelengths required for long-distance data transmissions," says the article from Popular Science online. Is it really impossible to hack this new fiber? Click here to read the rest of the story and the comments, which both challenge and support this new unbreakable Quantum Broadband Network.
