摘要

激光束衍射和湍流可能会降低卫星对地面通信中CV-QKD的安全密钥速率。使用先前导出的离散四态调制和反向调节公式，我们突出了产率超过50 Mbps的参数，并估计了由于湍流导致的百分比降低。

Laser Beam Propagation Effects on Secure Key Rates for Satellite CV-QKD with Discrete Modulation

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.
