Characterizing quantum systems through experimental data is critical to applications as
diverse as metrology and quantum computing. Analyzing this experimental data in a robust …

Today's quantum computers are composed of tens of qubits interacting with each other and
the environment in increasingly complex networks. To achieve the best possible …

The topics of this thesis are based on circuit quantum electrodynamics (cQED), a theoretical
and experimental platform allowing the study of light--matter interaction. This platform is rich …
