Title (EN) SIGNAL GENERATING SYSTEM FOR EFFICIENCY AND HARDWARE REDUCTION
(FR) SYSTÈME DE GÉNÉRATION DE SIGNAL POUR L'EFFICACITÉ ET LA RÉDUCTION DU MATÉRIEL
Abstract:
(EN) A signal generating system is provided. The signal generating system provides a microwave signal to a plurality of qubits. The signal generating system includes a generator, an oscillator, a mixer, and a splitter. The oscillator generates an oscillator signal including a constant frequency. The generator generates a generator signal including an initial frequency. The mixer is electrically coupled to the generator and the oscillator. The mixer combines the generator and oscillator signals to produce the microwave signal. The splitter is electrically coupled to the mixer. The splitter fans-out the microwave signal to a plurality of physical lines. Each of the plurality of physical lines is electrically connected to a corresponding one of the plurality of qubits.
(FR) L'invention concerne un système de génération de signal. Le système de génération de signal fournit un signal à hyperfréquence à une pluralité de bits quantiques. Le système de génération de signal comprend un générateur, un oscillateur, un mélangeur et un séparateur. L'oscillateur génère un signal d'oscillateur contenant une fréquence constante. Le générateur génère un signal de générateur contenant une fréquence initiale. Le mélangeur est relié électriquement au générateur et à l'oscillateur. Le mélangeur combine les signaux de générateur et d'oscillateur pour produire le signal à hyperfréquence. Le séparateur est relié électriquement au mélangeur. Le séparateur ventile le signal à hyperfréquence vers une pluralité de lignes physiques. Chacune de la pluralité de lignes physiques est reliée électriquement à un bit quantique correspondant de la pluralité de bits quantiques.
