Description 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 Ratio

2. 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)
