Quantum Materials: from Characterization to Resonator Measurements

Would you like to understand and address materials losses that are a key obstacle for the next generation of quantum technology? This webinar details how low-noise measurements with lock-in amplifiers can help you optimize your materials. Jim Phillips explains Hall measurements, RF reflectometry for quantum dot stability diagrams, and the Pound-Drever-Hall (PDH) technique for resonator characterization.

Professor 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. We show recent results using PDH to perform resonator center frequency and Q-factor measurements faster than is possible with the traditional VNA method.
