Quantum Materials: from Characterization to Resonator Measurements

This webinar explains how studying materials and resonators accelerates qubit development. Jim Phillips of Zurich Instruments discusses Hall measurements, RF reflectometry for quantum dot stability diagrams, and the Pound-Drever-Hall (PDH) technique for resonator characterization. Corey Rae McRae of CU Boulder and NIST Boulder dives into the use of microwave resonators as a tool to better understand superconducting qubit materials at millikelvin temperatures and ultralow powers. She shows recent results in which resonator center frequency and Q-factor measurements are performed faster using PDH than is possible with the traditional VNA method.
