Control of high-dimensional spatial entanglement via Gouy phase for high-performance quantum communication

The set of data is part of the pilot study on the control of high-dimensional spatial entanglement via Gouy phase for high-performance quantum communication. The method consists of producing a series of phase-slit images on a spatial light modulator (SLM), which allows one to characterize the spatial profile of the field on the SLM. The ultimate goal of such study is that through the spatial Gouy phase of the photons traversing the slits, one can assess the entanglement between the SPDC photons.The study covered a spontaneous parametric down conversion source (SPDC) and an interference setup, including the computed masks for the SLM to display fringes.The set of data contains:1-Laguerre Gaussian beam pattern obtained from a Gaussian beam after being reflected by the SLM (ran the SLM with an OAM phase displayed to confirm its correct operation).2-2D images of the interference pattern for different width of slits3- 3D Images of the interference pattern for classical light with different polarization shining onto the SLM (only-phase SLM sensitive to polarization).4-Python script to read .bmp format figure and calculate the intensity of the interference pattern.5-Python script to create phase masksThe research was carried out within Miniatura 7 project (2023/07/X/ST2/01358) granted by National Science Center (Poland).
