Fig. 4: Comparison of extracted binary sequences from parallel chaos (CH4 and CH5).
From: Scalable parallel ultrafast optical random bit generation based on a single chaotic microcomb
Amplitude histogram distributions (in integer representation) for the extracted binary sequences from CH4 and CH5 by retaining (a) 16-LSBs and (b) 8-LSBs; Power spectra of the extracted binary sequences from CH4 and CH5 by retaining (c) 16-LSBs and (d) 8-LSBs; (e) XOR bitmap image and (f) cross-correlation function (CCF) between the extracted binary sequences from CH4 and CH5 by retaining 8-LSBs
