La distribution quantique de clés offre la possibilité d’une cryptographie dont la sécurité est démontrée par les lois de la physique quantique. De premiers systèmes commerciaux de cette technologie sont aujourd’hui disponibles. Cette thèse s’intéresse plus particulièrement aux protocoles à variables continues, dont l’implémentation pratique s’approche des techniques modernes de transmissions numériques sur fibre optique. En exploitant ces techniques, on réalise un système expérimental de distribution quantique de clés à variables continues à haut débit.Quantum key distribution offers the possibility of cryptography whose security is demonstrated by the laws of quantum physics.
