FPGA-Based Synchronization of Frequency-Domain Interferometer for QKD

FPGA-Based Synchronization of Frequency-Domain Interferometer for QKD

In this article, we propose and experimentally demonstrate a novel synchronization method for quantum key distribution (QKD) systems. The method consists of maximizing the visibility of frequency-domain interference of optical sidebands about an optical carrier at the receiver node. The sidebands ar...
