Passive polarization and phase stabilization scheme for Twin-Field QKD
Christiano M. S. Nascimento, Felipe Calliari, Guilherme P. Temporão
Twin-Field Quantum Key Distribution requires first-order interference between coherent states sent by Alice and Bob in a mid-station Charlie. In order to obtain stable operation an…
Perturbative nonlinear feedback forces for optical levitation experiments
Oscar Kremer, Daniel Tandeitnik, Rafael Mufato +6
Feedback control can be used to generate well-determined nonlinear effective potentials in an optical trap, a goal whose applications may range from non-equilibrium thermodynamics…
A Fiber Measurement System with Approximate Deconvolution Based on the Analysis of Fault Clusters in Linearized Bregman Iterations
Yuneisy Garcia Guzman, Felipe Calliari, Gustavo C. Amaral +1
Automatic detection of faults in optical fibers is an active area of research that plays a significant role in the design of reliable and stable optical networks. A fiber measureme…
Alignment-free characterization of polarizing beamsplitters
Felipe Calliari, Pedro Tovar, Christiano Nascimento +3
Traditional methods for measurement of Polarizing Beamsplitter (PBS) parameters, especially the extinction ratio, require highly polarized light sources, alignment procedures and/o…
FPGA-Embedded Linearized Bregman Iterations Algorithm for Trend Break Detection
Felipe Calliari, Gustavo C. Amaral, Michael Lunglmayr
Detection of level shifts in a noisy signal, or trend break detection, is a problem that appears in several research fields, from biophysics to optics and economics. Although many…
Fast Polarization Switch for Polarization-Based Quantum Communication
Vinicius M. Lima, Felipe Calliari, Joaquim D. Garcia +4
We present a complete optoelectronic unit for polarization visualization, switching and control. The system is based on an FPGA unit and comprises: an acquisition unit containing a…
