Estimation of high-dimensional unitary transformations saturating the Quantum Cramér-Rao bound
J. Escandón-Monardes, D. Uzcátegui, M. Rivera-Tapia +2
We propose an estimation procedure for -dimensional unitary transformations. For , the unitary transformations close to the identity are estimated saturating the quantum Cr…
Transmission of optical communication signals through ring core fiber using perfect vortex beams
Nelson Villalba, Cristóbal Melo, Sebastián Ayala +10
Orbital angular momentum can be used to implement high capacity data transmission systems that can be applied for classical and quantum communications. Here we experimentally study…
Non-Markovianity in High-Dimensional Open Quantum Systems using Next-generation Multicore Optical Fibers
Santiago Rojas-Rojas, Daniel Martínez, Kei Sawada +5
With the advent of quantum technology, the interest in communication tasks assisted by quantum systems has increased both in academia and industry. Nonetheless, the transmission of…
Partial coherence and coherence length in StimPDC
Gustavo Henrique dos Santos, Raphael César Souza Pimenta, Rafael de Morais Gomes +2
In parametric down conversion, a nonlinear crystal is pumped by a laser and spontaneous emission takes place in signal and idler modes according to the phase matching conditions. A…
