The Qubit Readout RF Module (QRM-RF) stands as the definitive solution for multi-qubit readout within the 2 to 18.5 GHz frequency range. It seamlessly integrates inputs and outputs, supplying all the necessary tools for multiplexed resonator readout, RF-reflectometry, and spectroscopy measurements. This integration simplifies complex experimental setups by consolidating multiple functionalities into a single module.

The QRM-RF merges internal up- and down-conversion stages and Q1 advanced sequence processors. This design enables the direct acquisition and generation of RF signals with a large variable gain and maintains a high Spurious-Free Dynamic Range (SFDR) across the entire frequency range. The module’s onboard data processing capabilities facilitate complex integration functions, qubit state thresholding, and averaging to further enhance the QRM-RF's efficiency. Feedback applications can be managed by fast scalable feedback in ∼350 ns, facilitated by the LINQ protocol with all-to-all connectivity in the whole Cluster mainframe.
