Abstract

We experimentally validate the feasibility of wavelength-division multiplexing for continuous-variable quantum-key-distribution, transmitting four 600 MBaud probabilistically-shaped 256-QAM signals with 4 GHz spacing, achieving total 254.6 Mb/s average secret key rate.

Frequency-Division Multiplexed CV-QKD System

Jaehyeok Han, Donghyeok Lee, Minseok Ryu +3 more

We propose a frequency-division multiplexed (FDM) continuous-variable quantum key distribution (CV-QKD) system with enhanced spectral efficiency through optimized channel spacing of low-symbol-rate signals. A four-channel 10-Mbaud FDM-CV-QKD system was experimentally demonstrated using Gaussian modulation, a transmitted local oscillator, and homodyne detection. Despite the inter-channel interference, under a finite-size scenario (m=1.25x10^6), the system achieved a 3.6-fold back-to-back secret key rate gain and outperformed the single-channel frequency-upconverted signal up to 26.8 km.
