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.

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.

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.

Quantum Fisher Information from Randomized Measurements [PDF]
Physical Review Letters, 2021 The quantum Fisher information (QFI) is a fundamental quantity of interest in many areas from quantum metrology to quantum information theory. It can in particular be used as a witness to establish the degree of multi-particle entanglement in quantum many-body-systems.

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.

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.
