Some of the country’s most important photonics firms include ID Quantique of Geneva, a quantum photonics specialist... [5]

ID Quantique: World Cup Security Uses Physics To Thwart Hackers

{ID Quantique / Gregoire Ribordy, CEO}
(06/21/2010)
"The goal is to ensure not only the confidentially but also the integrity of this information," said Gregoire Ribordy, CEO of ID Quantique in Geneva, which developed the system with Senetas Corporation in Australia... [3]

U. of Bristol: Theoretical Breakthrough for Quantum Cryptography

{University of Bristol / Anthony Laing}
(03/07/2010)
The world of cryptography is currently undergoing a quantum revolution. The weird laws of quantum mechanics allow cryptographers to create codes that guarantee perfect secrecy. Until recently, the best cryptographers could aim for was just pretty good secrecy with codes that were always compromised in some way or another. Quantum cryptography, on the other hand, is perfect: theoretically and practically secure. [1]

U. of Toronto: Quantum crack in cryptographic armour

{University of Toronto in Ontario / Prof. Hoi-Kwong Lo}
(05/20/2010)
In theory, quantum cryptography--the use of quantum systems to encrypt information securely--is perfectly secure. In practice, however, no quantum cryptographic system is perfect and errors will creep in owing to mundane environmental noise. Quantum physicists have calculated that as long as the mismatch between Alice's and Bob's keys is below a threshold of 20 percent, then security has not been breached... [4]

U. of Geneva: Science, Spirituality, and Some Mismatched Socks

{U. of Geneva & ID Quantique / Prof. Gisin}
(05/09/2009)
An electronic key is usually written in the computer binary code of "ones" and "zeros." Quantum physics permits a more sophisticated approach. The same "ones" and "zeros" can now be encoded by using the properties of photons, like spin. If someone intercepts a photon-based message, the spins change. The receiver then knows the key has been compromised.
Dr. Gisin is a founder of ID Quantique SA in Switzerland. The company's similar encryption tool is used by online lottery and poker firms to safely communicate winning numbers and winning hands. Votes cast in a recent Swiss federal election were sent in a similar way. [2]
Prof. Gisin and ID Quantique are also involved in the QCrypt nano-tera.ch project
