CV-QKD transmits quantum signals using coherent states, which are detected by the receiver through coherent detectors, similar to those commonly used in classical telecommunications. In this study, we evaluate its ability to coexist with classical data signals over the same optical fiber.

[Research Paper] Work of QUARTER Lead, LuxQuanta, accepted at the prestigious OFC Conference, studies the efficacy of the Savitzky-Golay Filter in reducing Phase Noise in CV-QKD. The results are promising in increasing maximum achievable distances.
