The results of the quantum tomography measurement performed on the laser-pumped entangled photons source with uncompensated walk-off

In this dataset, we present the results of the quantum tomography experiment performed on the setup without the crystal which compensates the walk-off of the entangled photons. The setup scheme is shown in the file `quantum-tomography-experiment-scheme-shaded-elements.png`. This experiment was conducted at the Department of Optoelectronics laboratory at the Silesian University of Technology in December 2025.
