Symmetries of Quantum Fisher Information as Parameter Estimator for Pauli Channels under Indefinite Causal Order
Quantum Fisher Information is considered in Quantum Information literature as the main resource to determine a bound in the parametric characterization problem of a quantum channel by means of probe states. The parameters characterizing a quantum channel can be estimated until a limited precision se...
