Tracking time-varying signals with quantum-enhanced atomic magnetometers

Data used to generate figures for the publication "Tracking time-varying signals with quantum-enhanced atomic magnetometers" (https://arxiv.org/abs/arXiv:2503.14793).The dataset includes the numerical solution of stochastic differential equations modelling the evolution of the state of an optically-pumped atomic magnetometer whose state is estimated and controlled with a combination of an EKF+LQR. The numerical solution is performed for experimentally-realistic parameters, as described in detail in the manuscript.All simulations were performed using Julia Programming Language.Each zip file corresponds to a specific figure in the manuscript and contains .txt files with individual trajectories of physical quantities (e.g., spin components, variances, squeezing parameters, estimation errors). Folder and file names follow a consistent structure to reflect simulation parameters.A detailed description of all data structures, variables, and file contents is provided in the included in README.txt.
