C3

C3 is an integrated toolset designed for the control, calibration, and characterization of physical systems, particularly relevant for quantum devices. Its primary goal is to close the loop between different stages of experimental work:

• Open-loop control optimization
• Control pulse calibration
• Model-matching based on calibration data

The package offers a simple Python API, facilitating integration with various experimental setups. It provides a framework to implement and test advanced control techniques and analyze experimental data for system identification and calibration. Documentation and examples are available to assist users.
