Data supporting 'Experimental demonstration of confidential communication with quantum security monitoring'

Data measured for the paper Gong, Y., Wonfor, A., Hunt, J.H. et al. Experimental demonstration of confidential communication with quantum security monitoring. Sci Rep 11, 21686 (2021). https://doi.org/10.1038/s41598-021-01013-y. As this paper describes a communication system which can produce many Terabytes of data per hour, we did not store the data passing through our system. In the experiment we only collected the measured excess noise of the received signal and the calculated channel transmission loss. These are available in the attached spreadsheet, in which we present the data and analysis for figures 4 ,6, and 7 within the paper. For each sample point, it is the average value of 10^5 data samples being transmitted - we do not preserve all of the original data samples. In this file, we present the data to demonstrate the system performance under the fibre tapping attack, e.g. the channel transmission loss and the CUSUM analysis of it. And then we present the similar analysis for both channel transmission and excess noise to demonstrate the system performance under the correlated jamming attack. The CUSUM analysis results are also included. We recorded both the upper and lower bound of the results. The detection point can be found according to the journal paper.
