| The Improvement of Security for Continuous-Variable Quantum Key Distribution with Imperfect Phase Modulation | QCRYPT 2020 | Zhengwen Cao, Geng Chai, Chen He |
The signal of the photon must be phase modulated by Phase Modulation(PM), which plays a very important role in a continuous-variable quantum key distribution system. However, there may exits a drift of voltage in actual system. In this paper, we study the influence of the imperfect PM on the system performance of the CVQKD system. The result shows that the imperfect PM can threat the security of CVQKD system and choosing a reasonable noise module can be passively improved the security of system. We also propose a way to contain modulation noise in practical CVQKD systems. |
