Quantum interference between spectral bandwidth mismatched photonsGeneral Information:Title of Manuscript: Quantum interference between spectral bandwidth mismatched photonsAuthors: Jan Krzyżanowski, Jerzy Szuniewicz, Sanjay Kapoor, Filip Sośnicki, Michał KarpińskiCorresponding Author Email: jan.krzyzanowski@fuw.edu.plInstitution: Faculty of Physics, University of Warsaw, Pasteura 5, 02-093 Warszawa, PolandPreprint DOI: https://doi.org/10.48550/arXiv.2601.12129Dataset License: CC-BY 4.0Description of the Data:This dataset contains experimental data supporting the figures in the manuscript mentioned above. The data capture quantum interference patterns and spectral measurements of bandwidth-mismatched photons, specifically focusing on Hong-Ou-Mandel (HOM) interference with and without a time-lens mechanism.File Structure and Contents:The dataset is organized into two main directories corresponding to specific figures in the manuscript.1. Folder: `HOM` (Hong-Ou-Mandel)Description: Contains data for Figure 4. These files represent the HOM dip measurements.File format: .csv (Comma Separated Values)`hom_interference_with_time_lens.csv`Data representing the interference pattern when the time lens setup was active.Column 1: Time delay (in seconds)Column 2: Coincidence Counts (per second)Column 3: Coincidence to Singles Ratio`hom_interference_without_time_lens.csv`Data representing the interference pattern without the time lens.Column 1: Time delay (in seconds)Column 2: Coincidence Counts (per second)Column 3: Coincidence to Singles Ratio2. Folder: `Spectra`Description: Contains data for Figure 3. These files represent time-of-flight spectral measurements.File format: .csv and .dat (ASCII text)`classical_reference.csv` Spectrum of the classical reference signal. Columns: Wavelength (nm), Intensity (mW)`with_time_lens_heralded.dat`Heralded coincidence data with the time lens on. Red trace in Figure 3(c).Columns: Time (ps), Coincidence Counts (per second)`with_time_lens_unheralded.dat`Single photon count rates with the time lens on. Blue trace in Figure 3(c).Columns: Time (ps), Counts (per second)`without_time_lens_heralded.dat`Coincidence data collected with the time lens off. Red trace in Figure 3(b).Columns: Time (ps), Coincidence Counts (per second)`without_time_lens_unheralded.dat`Single photon count rates with the time lens off. Blue trace in Figure 3(b).Columns: Time (ps), Counts (per second)
