The C3 package is intended to close the loop between open-loop control optimization, control pulse calibration, and model-matching based on calibration data.
pip install c3-toolsetIf you want to try out the bleeding edge (possibly buggy) version under development:
pip install c3-toolset-nightlyThere is no official support for c3-toolset on Apple Silicon devices, but you can check the CONTRIBUTING.md for instructions on setting up an experimental version.
C3 provides a simple Python API through which it may integrate with virtually any experimental setup. Contact us at c3@q-optimize.org.
The paper introducing C3 as a scientific concept can be found in Wittler2021. Software and implementation details are described in SahaRoy2022.
Documentation is available here on RTD.
