Secure 100 Gb/s IMDD transmission over 100 km SSMF enabled by quantum noise stream cipher and sparse RLS-Volterra equalizer

Quan Yu, Yang Wang, Di Li, Haiping Song, Yudi Fu, Xingxing Jiang, Linbojie Huang, Mengfan Cheng, Deming Liu, Lei Deng
2020 IEEE Access  
INDEX TERMS Optical fiber communication, sparse RLS-Volterra equalizer, quantum noise cipher stream.  ...  In our scheme, a calculated detection failure probability of 98.72% is achieved. Apparently, more quantum noise contributes to higher security but the worse signal to noise ratio.  ...  Quantum noise stream cipher (QNSC) is another method to secure the transmission by utilizing quantum noise to mask the signal based on the Y-00 protocol at the physical layer [14] - [17] .  ...

Polarization and Index Modulations: a Theoretical and Practical Perspective [article]

Pol Henarejos
2018 arXiv   pre-print
Consequently, the goal of this thesis is twofold: first, we aim at increasing the current capacity of point-to-point and point-to-multipoint links.  ...  Thus, the study of polarization in these systems is essential.  ...  In the latter case, no information is placed in the hops and its objective is to exploit frequency diversity and increase security at physical level.  ...
