Reconstruction of single-photon emission with a self-calibrated wQED device based on a transmon qubit

The dataset contains frequency-domain and time-domain measurements acquired from a microwave single-photon source and power-sensor device based on a superconducting transmon qubit, as reported in D. Labranca et al., “Reconstruction of single-photon emission with a self-calibrated wQED device based on a transmon qubit,” New Journal of Physics 27 (2025) 073001, https://doi.org/10.1088/1367-2630/ade736.
The files are from frequency domain measurements (VNA and Spectrum Analyzer) and time domain measurements (digitizer) of a microwave single-photon source and power sensor device (superconducting transmon qubit).
Both files can be read as python dictonaries of arrays (or matrices) and they feature explanatory key names.
- ReflectionMeasurement.mat : Contains data for the reflection measurement at the emission port of the qubit. Two matrices are included: one with the qubit detuned by several GHz ("offRes" flag) and one with the qubit at the center of the bandwidth analyzed ("onRes" flag)
- SpectrumAnalyzerMeasurement.mat: Contains the SA traces measured for a VNA tone with power "Pvna_corrected".
- RabiOscillations.mat: Contains mode matched Rabi emission of the single-photon source and it is used to calibrate the qubit drive pulses.
- QuadratureDistribution.mat: Contains the mode-matched emission of the source after preparing the ground, excited and superposition states of the qubit.
