Resonator Characterization via the Pound-Drever-Hall Method

21.08.2023

PDH Block diagram

This blog discusses methods for measuring the frequency fluctuations and quality factor, 𝑄, of a resonator. Resonators are physical systems that naturally oscillate at a well-defined frequency. At this resonant frequency, energy exchanges periodically between two forms, for example, kinetic and spring energy as in a scanning probe microscope’s cantilever...

Quantum Materials: from Characterization to Resonator Measurements - Q&A

26.06.2023

QT Webinar Physic Today

In this webinar, we discussed transport measurements on materials for quantum computing, why studying resonators accelerates development of materials used for quantum computing by yielding a wealth of information, and how to measure resonators effectively with the Pound-Drever-Hall method. The recording of the full webinar can be found here...

Quantum Material Characterization for Streamlined Qubit Development

03.01.2022

Basic decoherence types

In this webinar, we covered the material properties that are most important to consider when developing qubits with longer coherence times and looked into how to characterize these materials accurately and efficiently. By focusing on the fundamental properties of the materials, simpler fabrication methods and experimental setups can be used...
