| Abstract | A current device readout system and a method for reading a current state of a current device are provided. The system includes a tunable resonator (16) having a resonant frequency that is associated with a current state of a current device (12) being configured as flux qubit. The tunable resonator can be configured to receive a tone signal having a predetermined frequency from a feedline (20) to determine the current state of the current device. The system also includes an isolation device (18) inductively interconnecting the tunable resonator and the current device. The isolation device is configured as a quantum flux parametron and can be tunable to isolate the current device in a first state and to facilitate the determination of the current state of the current device in a second state.
L'invention concerne un système de lecture de dispositif de courant et un procédé permettant de lire un état courant d'un dispositif de courant. Le système comprend un résonateur accordable (16) présentant une fréquence de résonance qui est associée à un état courant d'un dispositif de courant (12) configuré sous la forme d'un bit quantique de flux. Le résonateur accordable peut être configuré pour recevoir un signal de tonalité présentant une fréquence prédéterminée à partir d'une ligne d'alimentation (20) afin de déterminer l'état courant du dispositif de courant. Le système comprend également un dispositif d'isolation (18) interconnectant par induction le résonateur accordable et le dispositif de courant. Le dispositif d'isolation est configuré sous la forme d'un paramétron à flux quantique et peut être accordable afin d'isoler le dispositif de courant dans un premier état et de faciliter la détermination de l'état courant du dispositif de courant dans un second état. |
