WB2.2 - LASER BEAM PROPAGATION EFFECTS ON SECURE KEY RATES FOR SATELLITE CV-QKD WITH DISCRETE MODULATION
Abstract
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.
WB2.3 - DISCRETIZED GAUSSIAN MODULATION-BASED CONTINUOUS VARIABLE (CV)-QKD
Abstract
Abstract
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 collective attacks.
