Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Raw and processed oscilloscope data for the experiment on distributed quantum sensing in a continuous variable entangled network, published in Nature Physics (2019), https://doi.org/10.1038/s41567-019-0743-x
The dataset contains the following three files in HDF5 format:
(1): distsens_raw.hdf5 --- The raw oscilloscope traces of the homodyne output. (The file is as large as 7.66GB!)
(2): distsens_phasecalibration.hdf5 --- The oscilloscope traces for phase calibration.
(3): distsens_spectra.hdf5 --- averaged power spectral density results processed from the raw oscilloscope traces. This file is only 15.9 MB, and is provided in case (1) is too slow to download or process.
A Jupyter Notebook "distributed_sensing.ipynb" can be found at https://github.com/qpit/distributed-quantum-sensing. This notebook documents and run the data analysis of the files provided here.
