Building the Manuscript

The entire analysis pipeline and manuscript can be built with a single command:

make

This will:

1. Process raw experimental data
2. Generate all plots and tables
3. Compile the LaTeX manuscript to PDF

Requirements

• Python 3.7+ with packages:
  • pandas
  • numpy
  • matplotlib
  • pyprojroot
  • papermill
  • jupyter
• LaTeX distribution (e.g., TeXLive, MikTeX)
• Make

Data

The data/raw/experimental_data.csv file contains measurements from 35 participating laboratories (34 after quality control). Each row represents one experiment with the following key variables:

• Bell Parameter (S)
• Entanglement Fidelity
• Visibility
• Detector specifications
• Environmental conditions
• And more...

Reproducibility

All analysis is fully reproducible. The Makefile ensures correct execution order and dependency tracking. To rebuild from scratch:

make clean
make
