Seeded SU(1,1) interferometry for Fourier-domain optical coherence tomography
Alejandra A. Padilla, Valentina Gacha, Daniel F. Urrego +1
We demonstrate Fourier-domain optical coherence tomography (FD-OCT) based on a seeded SU(1,1) interferometer. Multilayer objects are probed with broadband light centered at 1550nm,…
Constant sensitivity birefringence metrology using vector vortex beams
Gabriela Flores-Cova, Daniel Salamanca-Roldán, Carmelo Rosales-Guzmán +2
Differential Interference Contrast (DIC) microscopy and chiral analysis are two imaging techniques that measure the birefringence, i.e., the phase difference introduced by a sample…
Below-shot-noise capacity in phase estimation using nonlinear interferometers
Cristofero Oglialoro, Gerard J. Machado, Felix Farsch +7
Over the past decade, several schemes for imaging and sensing based on nonlinear interferometers have been proposed and demonstrated experimentally. These interferometers exhibit t…
Quantum Interference of Distinguishable Photons Based on Spatially-Resolved Measurements
Miguel Angel Gonzalez, Alejandra Alarcón, Andres Camilo Quintero +5
We present experimental results demonstrating the quantum interference of two photons distinguishable in their transverse momenta, each entering the input ports of a balanced beam…
Decoherence-assisted quantum key distribution
Daniel R. Sabogal, Daniel F. Urrego, Juan Rafael Álvarez +3
We present a theoretical and experimental study of a controllable decoherence-assisted quantum key distribution scheme. Our method is based on the possibility of introducing contro…
Non-mechanical steering of the optical beam in spectral-domain Optical Coherence Tomography
Daniel F. Urrego, Gerard J. Machado, Juan P. Torres
We demonstrate in a {\it proof-of-concept} experiment spectral-domain optical coherence tomography where steering of the optical beam that probes the sample in a transverse scan do…
Quantum-inspired protocol for measuring the degree of similarity between spatial shapes
Daniel F. Urrego, Juan P. Torres
We put forward and demonstrate experimentally a {\it quantum-inspired} protocol that allows to quantify the degree of similarity between two spatial shapes embedded in two optical…
A quantum-inspired Fredkin gate based on spatial modes of light
Daniel F. Urrego, Dorilian Lopez-Mago, Verónica Vicuña-Hernández +1
Distinguishing between strings of data or waveforms is at the core of multiple applications in information technologies. In a quantum language the task is to design protocols to di…
Controlling Non-Markovian Dynamics Using a Light-based Structured Environment
Daniel F. Urrego, Jefferson Flórez, Jiří Svozilík +2
We present the experimental control of Non-Markovian dynamics of open quantum systems simulated with photonic entities. The polarization of light is used as the system, whereas the…
Implementation and characterization of a controllable dephasing channel based on coupling polarization and spatial degrees of freedom of light
Daniel F. Urrego, Juan-Rafael Álvarez, Omar Calderón-Losada +3
We present the experimental implementation and theoretical model of a controllable dephasing quantum channel using photonic systems. The channel is implemented by coupling the pola…
