Efficiently evaluating Holevo, RLD and SLD Cramér-Rao bounds for multiparameter quantum estimation with Gaussian states
Abstract
Quantum estimation with continuous variable systems faces challenges in deriving accessible and practical results for practitioners. Here, the authors present a unified framework for computing multiparameter bounds for Gaussian states, demonstrating their approach through semidefinite programming, which could significantly enhance precision in quantum measurements.
