Description du projet
La photonique sur puce améliorera l’accès au stockage sécurisé des données et à leur transmission rapide
La cybersécurité représente un défi grandissant au vu de la quantité gigantesque de données sensibles qui est transmise dans le monde et des méthodes de plus en plus sophistiquées auxquelles recourent les acteurs malveillants. Les réseaux de distribution quantique de clés (QKD pour «quantum key distribution») visent à relever ce défi, en utilisant les propriétés physiques des photons pour coder les informations et les lois fondamentales de la physique quantique pour les chiffrer. Les vitesses de transmission sont cependant limitées et les coûts, prohibitifs. La PME française Quandela a mis au point un émetteur monophotonique plus efficace et plus précis. Elle entend l’installer sur une puce, prête à être intégrée de manière rentable dans les réseaux QKD. Le projet EQUALITY, financé par l’UE, aide l’équipe à optimiser la technologie et à préparer le plan d’affaires en vue de sa commercialisation.
Objectif
Billions of consumers and thousands of companied depend on the security of network infrastructure to assure the safety of their data as it is bleamed around the world. At present, the security provided by traditional encryption algorithms depend on the fact that it takes a very long time for a traditional computer to solve the encryption that would reveal the protected data. However, advances in the domain of quantum computing and the development of efficient algorithms mean that it is becoming much easier to break down conventional encryption algorithms based on computational complexity. Quantum Key Distribution (QKD) networks aim to overcome this challenge by proposing secure lines of communication that have been encrypted using the fundamental laws of quantum physics. This is achieved through manipulation of physical properties of photons to encode information. However, many such networks remain expensive to set up and requires the support of a state-level entity, thus beyond the reach of consumers and companies. Furthermore, the transmission speeds achieved through current photon emitters remain relatively low, making transmitting complex data difficult. Quandela, a french SME founded in 2017 as a spin-off of the French Centre for Scientific Reseach (CNRS) proposes a revolutionary efficient emitter of single photons that would significantly increase the rates of information that could be efficiently transported through QKD networks. Thanks to a proprietary technology, Quandela's photon emitters are able to emit photons significantly more accurately and efficiently than the current products in the market. Quandela is specialized in building efficient chip-based quantum light sources. Due to its size and efficiency of photon emission, these chips could be easily integrated into a QKD network, thus significantly enhancing information transfer rates over longer distances. In addition to light sources, Quandela develops technological bricks for quantum applications.
