Characterizing Fisher information of quantum measurement
Rakesh Saini, Jukka Kiukas, Daniel Burgarth +1
Informationally complete measurements form the foundation of universal quantum state reconstruction, while quantum parameter estimation is based on the local structure of the manif…

Completeness Stability of Quantum Measurements
Rakesh Saini, Jukka Kiukas, Daniel Burgarth +1
We introduce a resource monotone, the completeness stability, to quantify the quality of quantum measurements within a resource-theoretic framework. By viewing a quantum measuremen…

Characterizing errors in parameter estimation by local measurements
Riddhi Ghosh, Alexei Gilchrist, Daniel Burgarth
The indirect estimation of couplings in quantum dynamics relies on the measurement of the spectrum and the overlap of eigenvectors with some reference states. This data can be obta…
