Quantum Fisher information power of quantum evolutions

Journal of Physics A: Mathematical and Theoretical
Abstract Quantum metrology is an important field in quantum information and plays a crucial role in quantum parameter estimation. Quantum Fisher information (QFI) is widely used to characterize the precision of quantum parameter estimation.

Transmission of Quantum Fisher Information through Fluctuating Quantum Fields

Annalen der Physik, 2018
AbstractTransmission 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.
