Towards Automated Microwave Measurements and Calibrations at Millikelvin Temperatures

The implementation of future large-scale solid-state quantum computation systems will require calibrated microwave measurements at millikelvin temperatures. These measurements are key for accurate characterization of superconducting microwave devices and waveforms in the cryogenic environment and for the optimization of quantum-classical interfaces in solid-state quantum computation systems. This will require automated cryogenic RF probing, and custom millikelvin temperature calibration standards and procedures. In this talk, we will present the progress made at NIST towards the development of these new measurement capabilities and address the challenges related to their application in the extremely cold and dark dilution fridge environment.
