Quantum cryptography comes of age

A data archiving network in Geneva claims to be the first to use quantum cryptography technology to secure data transfer.

Deckpoint and id Quantique, two private companies active in the field of information technology based in Geneva, Switzerland, and the University of Geneva, have announced the opening of a data archiving network secured using their quantum cryptography technology.

Current cryptographic techniques used to guarantee the confidentiality of data that’s transmitted over a network are based on complex mathematical algotithms. But in spite of the fact that they are used widely, they do not offer foolproof security. On the other hand, quantum cryptography exploits the laws of quantum physics to guarantee the confidentiality of data transmission.

The University of Geneva, where research on quantum cryptography started in the early 90’s, played a pioneering role in the development of the technology. At the end of 2001, four researchers, who were convinced of the potential of this technology, founded the company id Quantique to develop commercial applications.

And it was id Quantique and Deckpoint who joined forces to develop and implement this first data archiving network secured using quantum cryptography. Specifically, the data saved on a farm of 30 servers of the Deckpoint Housing Centre, in the Acacias district of Geneva, are replicated on servers located at the Cern Internet Exchange Point, in Meyrin, in the suburbs of Geneva. The distance between the two sites is about 10 kilometres.

“Quantum cryptography constitutes a revolution in the field of information security ” says Professor Nicolas Gisin, of the University of Geneva. “It is the only solution offering long term confidentiality and which cannot be compromised by scientific or technological advances “.
