Uncertainty principle and quantum Fisher information [PDF]
Annals of the Institute of Statistical Mathematics, 2006 We show that an inequality recently proved by Kosaki and Yanagi-Furuichi-Kuriyama [arXiv:quant-ph/0501152] has a natural geometric interpretation in terms of monotone metrics associated to Wigner-Yanase-Dyson information. Moreover we give a counterexample showing that the inequality does not hold for every monotone metric of this type.

Inequalities for quantum Fisher information [PDF]
Proceedings of the American Mathematical Society, 2008 In 2003 Luo proved an inequality relating the Wigner-Yanase information and the $SLD$-information. In this paper we prove that Luo's inequality is a particular case of a general inequality which holds for any regular quantum Fisher information. Moreover we show that this general inequality is a consequence of the Kubo-Ando inequality that states that ...

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.

Steered quantum coherence and quantum Fisher information in spin-chain system
Results in Physics, 2023 In this paper, we investigate steered quantum coherence, i.e., the l1 norm of steered coherence and the relative entropy of steered coherence, and the quantum Fisher information in the Gibbs state of two-qubit XXZ systems.

Fisher Information of Free-Electron Landau States
Entropy, 2021 An electron in a constant magnetic field has energy levels, known as the Landau levels. One can obtain the corresponding radial wavefunction of free-electron Landau states in cylindrical polar coordinates.

Protecting Quantum Fisher Information in Correlated Quantum Channels [PDF]
Annalen der Physik, 2019 AbstractQuantum Fisher information (QFI) has potential applications in quantum metrology tasks. QFI is investigated when the consecutive actions of a quantum channel on the sequence of qubits have partial classical correlations. The results showed that while the decoherence effect is detrimental to QFI, effects of such classical correlations on QFI are

npj Quantum Information, 2022 The quantum Cramér–Rao bound sets a fundamental limit on the accuracy of unbiased parameter estimation in quantum systems, relating the uncertainty in determining a parameter to the inverse of the quantum Fisher information. We experimentally demonstrate
