| 发明名称 | System and method for qubit readout | ||
| 摘要 | A system is provided for multiplexed readout of qubits. The system comprises a plurality of bandpass (BP) filter resonant sections that are each coupled to a different respective point on a read line, wherein each BP filter resonant section is coupleable to a respective qubit through a respective qubit readout resonator. The system further comprises a plurality of tunable couplers, wherein each tunable coupler is coupled between a respective BP filter resonant section and a qubit readout resonator, and a coupling controller that controls the coupling strength of each qubit to the read line by controlling the impedance of each tunable coupler of the plurality of tunable couplers. | ||
