On the Discretized Gaussian Modulation (DGM)- Based Continuous Variable-QKD
IEEE Access, 2019 To overcome the low reconciliation efficiency problem of Gaussian modulation (GM)-based-continuous variable (CV)-quantum key distribution (QKD), in this paper, we propose to use discretized GM (DGM)-based-CV-QKD. The proposed CV-QKD scheme has complexity

QKD-Enhanced Cybersecurity Protocols
IEEE Photonics Journal, 2021 Security of QKD is guaranteed by the quantum mechanics laws rather than unproven assumptions employed in computational cryptography. Unfortunately, the secret-key rates are way too low and transmission distances are limited. The post-quantum cryptography
