Fisher information of a single qubit interacts with a spin-qubit in the presence of a magnetic field
N. Metwally
In this contribution, quantum Fisher information is utilized to estimate the parameters of a central qubit interacting with a single-spin qubit. The effect of the longitudinal, tra…

Estimation of pulsed driven qubit parameters via quantum Fisher information
N. Metwally, S. S. Hassan
We estimate the initial weight and phase parameters ( of a single qubit system initially prepared in the coherent state and interacts with three different shape…
