Security bounds for unidimensional discrete-modulated CV-QKD: a Gaussian extremality approach
John A. Mora Rodríguez, John A. Mora Rodriguez, Maron F. Anka +3
Unidimensional (1D) Gaussian-modulated continuous-variable quantum key distribution protocols have been proposed as a way to simplify implementation and reduce costs through single…
Radial-angular coupling in self phase modulation with structured light
M. Gil de Oliveira, L. J. Pereira, A. S. Santos +3
In this work we study the evolution of an optical vortex undergoing self phase modulation inside a nonlinear Kerr medium. The intensity dependent phase evolution couples the angula…
Spin to orbital angular momentum transfer in nonlinear wave mixing
B. Pinheiro da Silva, W. T. Buono, L. J. Pereira +3
We demonstrate the spin to orbital angular momentum transfer in the nonlinear mixing of structured light beams. A vector vortex is coupled to a circularly polarized Gaussian beam i…
Orbital angular momentum mixing in type II second harmonic generation
Leonardo J. Pereira, Wagner T. Buono, Daniel S. Tasca +2
We investigate the non linear mixing of orbital angular momentum in type II second harmonic generation with arbitrary topological charges imprinted on two orthogonally polarized be…
Quantum and classical separability of spin-orbit laser modes
L. J. Pereira, A. Z. Khoury, K. Dechoum
In this work we investigate the quantum noise properties of polarization vortices in connection with an intensity based Clauser-Horne-Shimony-Holt inequality for their spin-orbit s…
Effects of spontaneous symmetry break in the origin of non-analytic behavior of entanglement at quantum phase transitions
L. Justino, Thiago R. de Oliveira
We present an example where Spontaneous Symmetry Breaking may effect not only the behavior of the entanglement at Quantum Phase Transitions, but also the origin of the non-analytic…
