Sécurité en cryptographie quantique utilisant la détection homodyne d'états cohérents à faible énergie

Abstract : This work is a reflection on some quantum key distribution protocols. The phase of low level energy coherent states to carry information. Two main tracks are developed. In the first one we study the effect of a differential mode on the phase modulation protocole using photon counts. The second one is derived from a reflection on the benefit of a double threshold on the homodyn detection measures.
