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…

Second-order moment equivalence of twisted Gaussian Schell model beams and orbital angular momentum eigenmodes
T. Ferreira, G. Santos, S. Ayala +5
We show that the covariance matrix of any cylindrically symmetric coherent orbital angular momentum (OAM) eigenmode with quantum number takes a universal form depending only…
