Programmable multi-photon quantum interference in a single spatial mode -- Data and code for simulations

Description of the data and file structure

This Dataset contains data files with experimental results for the manuscript "Programmable multi-photon quantum interference in a single spatial mode" (pre-print version at https://arxiv.org/abs/2305.11157).

The CSV files contain the measured output distributions of our time-bin interferometer, for the various experiments we run. In the first column is the number of counts detected and in the following columns the corresponding output modes. The counts were detected by post-processing the time-tags of the recorded single photon events (a detailed explanation can be found in the Supplementary Informations of the paper).The number of counts is reported for all possible combinations of output modes in order to reconstruct the entire output distribution of collisionless events.

The text file contains the data points of the time-bin HOM histogram shown in the paper.

Code/Software

We also provide the Jupyter Notebook (LoopExperiment.ipynb) we used to simulate the experiments, developed by Dr. Tobias Guggemos.

The Loop-based architecture is a photonic experiment, that allows scalable implementation of Boson Sampling and arbitrary unitaries on a photonic platform. It can be implemented as a single, sequenced or nested architecture.

We use the python framework Perceval to simulate our experiments. We simulate the conversion of the time-bin encoded setup as path encoded photonic qubits.

More details can be found in the Notebook.
