In this work, we present an educational activity aimed at measuring the
Wigner distribution functions of quantum states of light in the undergraduate
laboratory. This project was conceived by students from various courses within
the physics undergraduate curriculum, and its outcomes were used in an
introductory Quantum Optics course at the Universidad de los Andes in Bogot\'a,
Colombia. The activity entails a two-hour laboratory practice in which students
engage with a pre-aligned experimental setup. They subsequently employ an
open-access, custom-made computational graphical user interface to reconstruct
the Wigner distribution function for various quantum states of light. Given
that the testing phase coincided with the COVID-19 pandemic, we incorporated
the capacity to analyze simulated data into the computational user interface.
The activity is now part of the course syllabus and its virtual component has
proven to be highly valuable for the implementation of distance learning in
quantum optics.Comment: 10 pages, 5 figure
