Raw counts from prepare-and-measure experiments implemented on quantum processors

This dataset provides access to raw counts from prepare-and-measure experiments performed on quantum processors with the aim of certifying certain properties of the set of preparations based on the so-called umbrella-like configuration. pm_umbrella_prepcert_counts_all.zip contains the raw counts of each outcome b corresponding to each combination of preparation and measurement choices x and y in csv files associated with different experiments identified in the filenames. Metadata and results for the relevant witness and its estimated standard deviation are provided in metadata_and_results.pdf for each experiment. See https://doi.org/10.5281/zenodo.10723275 for details of an implementation on IBM quantum processors including scripts processing completed jobs.
