Quantum Fisher information width in quantum metrology
Science China Physics, Mechanics & Astronomy, 2018In scenarios of quantum metrology, the unitary parametrization process often depends on space directions. How to characterize the sensitivity of parameter estimation to space directions is a natural question. We propose the concept of the quantum Fisher information (QFI) width, which is the difference between the maximum and minimum values of the QFI ...

Entanglement detection via quantum Fisher information
Physical Review A, 2013We propose an entanglement criterion in terms of quantum Fisher information, which complements the criterion based on variance and local uncertainty relations [H. F. Hofmann and S. Takeuchi, Phys. Rev. A 68, 032103 (2003)]. We illustrate the significance of this criterion by showing that it can reveal entanglement undetectable by the variance method ...

Transmission of Quantum Fisher Information through Fluctuating Quantum Fields
Annalen der Physik, 2018AbstractTransmission of quantum Fisher information (QFI) of initially disentangled parties is studied and the results show that the indirect correlations generated by the environment, which is considered as a bath of fluctuating quantum fields, will help transmit the quantum information.

Thermal quantum Fisher information in quantum dot system
Solid State Communications, 2014Abstract Using the quantum Fisher information (QFI), we investigate the problem of the parameter estimation in quantum system dot (QDS) including the effects of different parameters. We find that the QFI is affected by the strength temperature and might be finite even for higher temperatures in the asymptotic limit. Furthermore, we show that there is
