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.
