Our reflectometry measurement uses a Nb superconducting spiral inductor, improving the quality factor of the tank circuit. Through an analysis of the reflected signal's amplitude and phase, we can discern crucial electronic properties of the quantum dots, including electronic temperature and tunneling rate, providing invaluable insights into their behavior and applications.
