On with global sensing
Virginia Water, 21 February 2025
Today, my colleagues and I have released a new preprint on the foundations of quantum sensing, one of the three pillars of quantum technologies: arXiv:2502.14817.
From the choice of ignorance priors and loss functions to the practical implementation of adaptive algorithms with optimal estimators, POVMs, and errors, this tutorial-style contribution provides a cohesive formulation of global quantum sensing, metrology, and estimation through Bayesian principles of symmetry and geometry.
Related ongoing work on practical sensing platforms includes arXiv:2410.10615, arXiv:2310.02771, and arXiv:2204.11816, where the concept of location-isomorphic parameter, on which our work rests, is experimentally validated.
This work is the result of an international collaboration across five universities: Siegen, Nottingham, Exeter, La Laguna, and Surrey.
