A Working, Quantum-Encrypted Intranet

I firmly believe this is as significant as the very first internet transmission some years back. If the technology is working and 100% secure, how long until it makes its way at least into government websites? This might be the end of the hacked by Chinese index pages!" Reader Kent adds "A New York based company, MagiQ Technologies, has begun selling units for commercial use while a group in Europe recently made the first quantum encrypted bank transaction in Vienna, Austria - April 2004. But the Boston network - though limited to three locations - is believed to be the first Internet-integrated system that runs continuously between multiple distant locations."

    I just wanted to pose the question, how can you prove that it has not been tampered with? You can't measure anything without changing the state, right? So you shouldn't really be able to prove that its secure either. Anyone else think that this is BS?

    This is completely false. This is not a sig.

    Don't miss this bit on how the EU is planning to use Quantum Crypto to subert and avoid the U.S.'s rampant digital espionage.

    Would the US government really allow a technology that it couldn't eavesdrop?

    Breaking quantum encryption would most likely net you a Nobel Prize in Physics, since it implies breaking QM.

    This is indeed a truly new level of encryption. We probably can't say 100%, but breaking quantum encryption is definately a different order of difficulty than breaking conventional encryption.
