Quantifying quantum-amplified metrology via Fisher information
Physical Review Research, 2022 We present a unified framework, based on quantum metrology concepts, for defining and quantifying deterministic noiseless quantum amplification of parameter-dependent processes, which plays an important role in increasing the precision of quantum sensing.

Mutual Information, Fisher Information, and Population Coding [PDF]
Neural Computation, 1998 In the context of parameter estimation and model selection, it is only quite recently that a direct link between the Fisher information and information-theoretic quantities has been exhibited. We give an interpretation of this link within the standard framework of information theory.

Fisher information of correlated stochastic processes
New Journal of Physics, 2023 Many real-world tasks include some kind of parameter estimation, i.e. the determination of a parameter encoded in a probability distribution. Often, such probability distributions arise from stochastic processes.

Fisher information of a black hole spacetime
Journal of High Energy Physics, 2023 Relativistic quantum metrology is the study of optimal measurement procedures within systems that have both quantum and relativistic components. Here we use Unruh-DeWitt detectors coupled to a massless scalar field as probes of thermal parameters in ...

Quantum Reservoir Parameter Estimation via Fisher Information
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022 In this study, we show that as a result of weak interaction of different information environments structured with a single probe qubit, these environments can perform binary classification of the information they contain.

SEMIPARAMETRIC IDENTIFICATION AND FISHER INFORMATION [PDF]
Econometric Theory, 2016 This paper provides a systematic approach to semiparametric identification that is based on statistical information as a measure of its “quality.” Identification can be regular or irregular, depending on whether the Fisher information for the parameter is positive or zero, respectively.

Estimating Fisher information in normal population with prior information
Statistica, 2007 This paper is contemplated to propose a class of shrunken estimators which is further used in constructing a class of preliminary test estimators for amount of information in complete samples from normal population when some ‘apriori’ or guessed value of

INTRODUCTION TO QUANTUM FISHER INFORMATION [PDF]
Quantum Probability and Related Topics, 2011 The subject of this paper is a mathematical transition from the Fisher information of classical statistics to the matrix formalism of quantum theory. If the monotonicity is the main requirement, then there are several quantum versions parametrized by a function. In physical applications the minimal is the most popular.
