Quantum key distribution offers the possibility of cryptography whose security is demonstrated by the laws of quantum physics. The first commercial systems of this technology are now available. This thesis focuses on continuous variable protocols, whose practical implementation is close to modern digital transmission techniques over optical fibers. By exploiting these techniques, we realize an experimental system for high speed continuous variable quantum key distribution.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 particulièremen...
