Mathematica codes: Quantum metrology through spectral measurements in quantum optics

This repository contains the Mathematica notebooks used to generate the main numerical results and figures presented in A. Vivas-Viaña and C. Sánchez Muñoz (2026), Quantum Metrology through Spectral Measurements in Quantum Optics (PRX Quantum 7, 010346) The provided code reproduces the calculations and plots associated with the main figures indicated in each notebook. Additional figures and auxiliary calculations that are not directly required for the main conclusions of the paper are not included (but are available upon request); however, they can be readily obtained using the provided code.
