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…
Brazilian Twin Photons 32nd anniversary
Renné Medeiros de Araújo, Raphael César Souza Pimenta, Lucas Marques Fagundes +4
We present a historical review of the development and impact of spontaneous parametric down-conversion (SPDC) in Brazil, marking over three decades since the first twin-photon expe…
Experimental Investigation of Twist Conservation in Nonlinear Optical Three-Wave Mixing
Gustavo H. dos Santos, André L. S. Santos Junior, Marcos Gil de Oliveira +7
We conduct an experimental investigation into the conservation of the twist phase in Twisted Gaussian Schell Model (TGSM) beams during both up- and down-conversion three-wave mixin…
Decomposing spatial mode superpositions with a triangular optical cavity
G. H. dos Santos, D. C. Salles, M. G. Damaceno +5
We demonstrate that a triangular cavity can operate as an efficient discriminator for Hermite-Gaussian optical modes. The process is applied to distinct fields produced by a Spatia…
