Applications of disentropy in the analysis of randomness generated by quantum random number generators
摘要
In the present work, the randomness measure based on the disentropy of the autocorrelation function is used to quantify the randomness of binary sequences produced by quantum random number generators (QRNG). A homemade QRNG based on vacuum fluctuations and the Quantis QRNG, developed by IDQuantique and whose data are available at http://qrng.ethz.ch/live/, are analyzed. Our results show that the disentropy of the autocorrelation is a useful tool for performance analysis of QRNGs.
