Continuous-variable quantum key distribution robust against polarization-dependent loss

HIGHLIGHTS

• who: Ying Guo and colleagues from the School of Computer Science and Engineering, Central South University, Changsha, China have published the article: Continuous-Variable Quantum Key Distribution Robust Against Polarization-Dependent Loss, in the Journal: (JOURNAL)
• what: The authors show the derivation of the excess noise due to the effect of PDL. In what follows, the authors propose a PPC scheme to mitigate the involved PDL, leading to the increased secret key rate of the PDM-based CVQKD system. In the following, the authors focus on the effect of 4SNR on system performance. The performance . . .
