Engineering entanglement, geometric phase and quantum Fisher information
of a three-level system with energy dissipation
Abstract
Quantum Fisher information (QFI) and geometric phase have recently been
performed different tasks in quantum information technology. We
investigate the QFI and entanglement of a three-level atom in
$\Lambda $ configuration interacting with a quantized
field mode by using linear entropy. We study the dynamical behavior of
the geometric phase based on the engineering of a three-level atomic
configuration. We analyze the effect of energy dissipation of the
dynamical properties of the geometric phase and the QFI as an
entanglement quantifier between the three-level atom and field. We
explore the correlation between the engineering geometric phase and QFI
in the absence and presence of energy dissipation effect. We have found
that the $\mathrm{QFI}$ is very sensitive to the
effect of the time dependent coupling and energy dissipation.
