Dataset needed to reproduce figures 3 and 4 of "Calibrated transmission and reflection from a multi-qubit microwave package". Included are raw (calibrated) S-parameter data a Python notebook to apply time domain gating and then display the S-parameters of the multi-qubit package (Fig. 3). Requires Scikit-rf (https://scikit-rf.org/) to be installed. a Python notebook to display the simulated impact of signal distortions on quantum gate fidelities of a qubit within the package (Fig. 4).
