Réseau de cryptographie quantique en fonctionnement depuis plus de 12'000 heures

GENÈVE, Suisse, October 9 /PRNewswire/ -- Le réseau quantique SwissQuantum a été mis en place à Genève par l'Université de Genève (UniGe), la Haute Ecole Spécialisée de Suisse Occidentale (HES-SO) et la société id Quantique dans le but de démontrer la maturité de la cryptographie quantique et ceci dans un réseau maillé. Contrairement aux autres réseaux quantiques, celui-ci est utilisé pour sécuriser du trafic réel et est testé indépendamment.

La cryptographie quantique est une technologie permettant de distribuer sur des liens optiques des clés de chiffrement dont la sécurité est garantie par les lois de la physique quantique. Pour Nicolas Gisin (UniGe) << il s'agit de la seule technologie garantissant une confidentialité à long terme. >>

Les trois liens de cryptographie quantique formant le réseau transmettent des clés de chiffrement entre ses trois noeuds. Ces clés sont ensuite utilisées pour chiffrer des communications, comme par exemple un lien 10 gigabit Ethernet entre le CERN et l'Université de Genève. Le Prof. Gérald Litzistorf de la HES-SO note << SwissQuantum est le réseau quantique le plus avancé à ce jour. J'ai été impressionné par le fait que cette technologie ne requière que des compétences standard dans le domaine des réseaux pour être utilisée. >>

Le réseau, déployé en avril 2009, est en fonctionnement depuis plus de six mois et a passé récemment la barre des 12'000 heures cumulées de fonctionnement. << Avec ce projet, nous apportons une démonstration claire que cette technologie est fiable, mûre et prête à être déployée >> explique Grégoire Ribordy, directeur d'id Quantique. Le fonctionnement du réseau SwissQuantum a été présenté cette semaine au salon ITU Telecom World à Genève et ses performances dévoilées lors d'une conférence le 8 octobre.

Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...

IoT is rapidly becoming mainstream as more and more investments are made into the platforms and technology. As this movement continues to expand and gain momentum it creates a massive wall of noise that can be difficult to sift through. Unfortunately, this inevitably makes IoT less approachable for people to get started with and can hamper efforts to integrate this key technology into your own portfolio. There are so many connected products already in place today with many hundreds more on the h...
Digital Transformation is much more than a buzzword. The radical shift to digital mechanisms for almost every process is evident across all industries and verticals.
