With the Cri/oFlex® platform, Delft Circuits has developed a range of standard line configurations for superconducting qubit control and readout, including Flux Bias, Microwave Drive, Signal, Readout, and Pump lines. These configurations have been validated for superconducting qubit applications and address the most common control and readout requirements. Combined into pre-assembled and tested I/O systems, they provide a scalable architecture from room temperature to the quantum processor.
