Quantum Material Characterization for Streamlined Qubit Development

In this webinar, Ed, Jim, Jelena and Clemens look at how lock-in amplifiers offer a prime way to probe and understand material properties relevant for qubit coherence while keeping measurement times and complexity to a minimum. They discuss the basic working principles of semi- and superconducting qubits and demonstrate how to characterize frequency and loss fluctuations in readout resonators, as also summarized in this blog post.
