Abstract

La red incluye segmentos de fibra optica (3) y equipamiento convencional (1, 2, 4), mientras que un sistema de distribucion cuántica de claves (QKD) dispone de dispositivos de intercambio de informacion mediante canal cuántico (7, 8). El sistema comprende al menos un filtro (6) para cada uno de los referidos dispositivos de intercambio (7, 8) y al menos un bloque de gestion de canales clásicos y cuánticos (5) que reduce el ruido en canales cuánticos y que presenta al menos funciones de: atenuacion de la potencia de insercion de los canales clásicos en la red; polarizaciones distintas en los diversos canales clásicos y cuánticos; y cambios de asignaciones de longitudes de onda tanto en canales clásicos como cuánticos.
