Characterization of quantum states of light by means of homodyne detection and reconstruction of Wigner functions

In this work, a continuous variable quantum tomography is presented. This is done using two approaches, one using simulated data and another one using data from measurements performed in the laboratory. The Radon inverse transform, under the approximation of filtered back projection, alongside the d...

Esto se realiza utilizando dos enfoques, uno con datos simulados y otro con datos de mediciones realizadas en el laboratorio. La transformación inversa del radón, bajo la aproximación de retroproyección filtrada, junto con los detalles sobre la implementación de la detección homodina balanceada necesaria para realizar la tomografía se explican claramente. Las matrices densidad en representación de cuadraturas y Fock también se obtienen de la función Wigner.
