摘要: L'invention concerne un dispositif de génération d'un signal optique pour l'échange quantique de clés, comprenant :
- une source photonique (501) générant au moins un flux d'impulsions,
- un transducteur CAN (503) convertissant les photons d'un flux d'impulsions en une suite binaire aléatoire,
- un modulateur d'état quantique (502) mettant les photons des impulsions dans un nombre et un état quantique défini par un mot de commande pour générer le signal optique à partir d'un des flux d'impulsions (501),
- des moyens de calcul numériques (504) :
o générant au moins une séquence aléatoire (505) ayant une distribution de probabilité et un rythme donnés à partir de la suite binaire aléatoire,
o générant le mot de commande (506) conformément au protocole d'échange de clés à partir de ladite au moins une séquence aléatoire.
L'invention concerne également une charge utile pour satellite comprenant un tel dispositif de génération d'un signal optique.-

摘要: A signal power pooling apparatus is provided, to improve flexibility of controlling a signal polarization direction. In embodiments of this application, the apparatus includes a first tunable coupler and a second tunable coupler. The first tunable coupler includes a first input port, a first straight-through port, a first coupling port, and a first isolation port. The second tunable coupler includes a second input port, a second straight-through port, a second coupling port, and a second isolation port. The first input port may be configured to receive a first horizontally polarized signal, and the first straight-through port may output a second horizontally polarized signal. The second isolation port is connected to the first coupling port, and the second coupling port is connected to the first isolation port. The second input port may receive a first vertically polarized signal, and the second straight-through port may output a second vertically polarized signal.
