Abstract

UN RECEPTOR CRIPTOGRAFICO (10) INCLUYE UN DETECTOR DE FOTONES (52, 54, 56, 58) DISPUESTO PARA DETECTAR FOTONES QUE LLEGAN DE FILTROS (22 Y 24). UN ACOPLADOR DE FIBRA (14) DISTRIBUYE ALEATORIAMENTE CADA FOTON RECIBIDO (16) DESDE UNA FIBRA OPTICA A UNO DE LOS CANALES DE FOTONES (81, 20). LOS FILTROS (22, 24) SON CADA UNO DE ELLOS INTERFEROMETROS DE MACH-ZEHNDER DESEQUILIBRADOS CON UN MODULADOR DE FASE (34, 44) EN UN BRAZO (28, 38). LOS FILTROS (22, 24) IMPONEN BASES DE MEDIDA NO ORTOGONALES SOBRE LOS FOTONES DENTRO DE LOS CANALES RESPECTIVOS (18, 20). UN PROCESADOR DE SEÑALES DERIVA UN CODIGO-CLAVE CRIPTOGRAFICO MEDIANTE EL ANALISIS DE LAS SEÑALES RECIBIDAS DE LOS DETECTORES DE FOTONES (52, 54, 56, 58).
