Raw data of "Two-mode bosonic state tomography with single-shot joint parity measurement of a trapped ion"

Dataset for "Two-Mode Bosonic State Tomography with Single-Shot Joint-Parity Measurement of a Trapped Ion" All the raw data are generated by ARTIQ (https://m-labs.hk/artiq/manual/index.html) system.Please refer to the ARTIQ manual for detailed format.We used h5py module to read the .h5 data files. Data format Inside each .h5 file, there is a key datasets, which contains the names of the datasets generated from the experiment. Each dataset is actually composed of 3 keys: {dataset}, {dataset}.parameters, and {dataset}.units. If the experiment contains $m$ scan parameters, then the {dataset} is a $N \times (2 + m)$ matrix. The first and the last columns represent the photon count and the shot index, respectively. The $m$ columns in the middle are the actual values of the scan parameters. {dataset}.parameters and {dataset}.units contain the names and units of the scan parameters, respectively. We used threshold-based state discrimination with threshold 1, where we read the state is the bright state $\left| \uparrow \right\rangle$ if the photon count is greater than 1. Due to the imperfect state detection, we rescaled the estimated spin population (see Appendix D2 of the paper). Until we start a systematic calibration routine for this, we manually check the detection contrast of a microwave Rabi oscillation. The systematic calibration records are included in detection_contrast.npz. It has two keys: microwave.amplitude and microwave.offset. They represent the oscillation amplitude (contrast) and the minimum of $\left| \uparrow \right\rangle$ state population, respectively. Each array is a matrix with 2 columns, where the first column is the timestamp and the second column is the measured value at each time. We used this records for the data acquired after this calibration is started, with linear interpolation. The timestamp of each data can be obtained using the key run_time in the .h5 file.
