Abstract

Laser beam diffraction and turbulence can potentially reduce secure key rates for CV-QKD in satellite to ground communications. Using previously derived formulas for discrete four-state modulation and reverse reconciliation, we highlight parameters that yield rates exceeding 50 Mbps and estimate percentage reduction due to turbulence.
