Fisher Information and Semiclassical Treatments [PDF]
Entropy, 2009 We review here the difference between quantum statistical treatments and semiclassical ones, using as the main concomitant tool a semiclassical, shift-invariant Fisher information measure built up with Husimi distributions.

Mutual information bounded by Fisher information
Physical Review ResearchWe derive a general upper bound to mutual information in terms of the Fisher information. The bound may be further used to derive a lower bound for the Bayesian quadratic cost. These two provide alternatives to other inequalities in the literature (e.g.,

On a Conjecture regarding Fisher Information [PDF]
Advances in Mathematical Physics, 2015 Fisher’s information measure I plays a very important role in diverse areas of theoretical physics. The associated measures Ix and Ip, as functionals of quantum probability distributions defined in, respectively, coordinate and momentum spaces, are the ...

Fisher Information and Mutual Information Constraints [PDF]
2021 IEEE International Symposium on Information Theory (ISIT), 2021 We consider the processing of statistical samples $X\sim P_θ$ by a channel $p(y|x)$, and characterize how the statistical information from the samples for estimating the parameter $θ\in\mathbb{R}^d$ can scale with the mutual information or capacity of the channel.

A Tutorial on Fisher information [PDF]
Journal of Mathematical Psychology, 2017 In many statistical applications that concern mathematical psychologists, the concept of Fisher information plays an important role. In this tutorial we clarify the concept of Fisher information as it manifests itself across three different statistical paradigms.

Sub-quantum Fisher information [PDF]
Quantum Science and Technology, 2021 Abstract The quantum Fisher information (QFI) plays a crucial role in quantum information theory and in many practical applications such as quantum metrology. However, computing the QFI is generally a computationally demanding task.

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.
