AbstractWe study the behaviors of quantum Fisher information (QFI) for an accelerated atom interacted with fluctuating electromagnetic vacuum near a perfectly reflecting boundary. The master equation that governs the atom evolution is firstly derived. In the case without boundary, the fluctuation and acceleration of electromagnetic vacuum always attenuate the QFI. Nevertheless, in the presence of a boundary, the degradation, oscillation, and maintaining of QFI are dependent on the atom-boundary distance, acceleration and polarization direction of atom. The boundary can efficiently shield QFI from the impact of the fluctuating electromagnetic vacuum and acceleration in some certain conditions and let us have more freedom of manipulating the precision of parameter estimation.Graphical abstract
