Discretized Gaussian Modulation-Based Continuous Variable (CV)-QKD [PDF]

2019 IEEE Photonics Conference (IPC), 2019
To overcome the low-reconciliation-efficiency problem of Gaussian modulation (GM)-based-CV-QKD, we propose to use discretized-GM-based-CV-QKD. This scheme has complexity and reconciliation-efficiency similar to discrete modulation (DM)-based-CV-QKD and at the same time solves for the problem of nonexistence of strict security proofs for DM-CV-QKD under

Enhancing Performance of Continuous-Variable Quantum Key Distribution (CV-QKD) and Gaussian Modulation of Coherent States (GMCS) in Free-Space Channels Under Individual Attacks With Phase-Sensitive Amplifier (PSA) and Homodyne Detection (HD)

Sensors
In recent research, there has been a significant focus on establishing robust quantum cryptography using the continuous-variable quantum key distribution (CV-QKD) protocol based on Gaussian modulation of coherent states (GMCS). Unlike more stable fiber channels, one challenge faced in free-space quantum channels is the complex transmittance ...

RF-assisted coherent detection based continuous variable (CV) QKD with high secure key rates over atmospheric turbulence channels

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
In this invited paper, a high-speed continuous-variable quantum key distribution (CV-QKD) system is investigated in the presence of atmospheric turbulence, which is enabled by employing the wavelength, polarization, and orbital angular momentum (OAM) states as degrees of freedom.
