Experiment catalogue
This is the QruiseOS library of characterisation experiments. Please click on an experiment in the navigation sidebar to read more about it.
As explained in Running a task, an experiment task consists of a measurement and an analysis of the data.
To leverage Qruise-defined measurements and analysis, they should be imported from the qruise.measurements and qruise.experiments modules, respectively.
In the two following tables, we link characterisation experiments with the corresponding measurement and analysis classes in QruiseOS.
Notice that sometimes, two different experiments share a same measurement class, like all three Amplitude Rabi experiments. This is because a measurement can be instantiated and run with different set of arguments (which reflect different intentions, like coarse or fine sampling).
