High-Dimensional Quantum Key Distribution via full Core-mode Encoding over Deployed Multicore Fibers
G. H. dos Santos, K. B. Sawada, N. Villalba +11
Quantum key distribution (QKD) provides information-theoretic security rooted in quantum physics, while high-dimensional (HD) encoding increases both noise tolerance and secret-key…

Sub-picosecond inter-core skew characterization in multicore fibers via Hong--Ou--Mandel interference
L. Lira Tacca, L. Marques Fagundes, M. Morales Lillo +9
Inter-core skew (ICS), the differential group delay between cores of a multicore fiber (MCF), is a critical parameter for both classical space-division multiplexed communications a…

FPGA-Based Adaptive Control for Phase Stabilization in Fiber-Optic Interferometers Using Correlated Photons
P. M. Berto, F. CampodÃnico, A. A. Matoso +5
Time-bin encoded photon pairs enable robust, decoherence-resistant transmission through optical fibers for long-distance quantum communication, where phase noise poses a critical l…
