Two-port microwave calibration at milliKelvin temperatures



Leonardo M. Ranzani, Lafe F. Spietz, Zoya Popovic, Jose A. Aumentado


In this work we introduce a system for 2-port microwave calibration at millikelvin temperatures operating at the coldest stage of a dilution refrigerator by use of an adapted thru-reflect-line algorithm. We show that this can be an effective tool for characterizing common 50 ω microwave components with better than 0.1 dB accuracy at temperatures that are relevant to many current experiments in superconducting quantum information.
