  In this manuscript, we investigate the effect of the white and color noise on
a accelerated two-qubit system, where different initial state setting are
considered. The behavior of the survival amount of entanglement is quantified
for this accelerated system by means of the concurrence. We show that, the
color noise enhances the generated entanglement between the two particles even
for small values of the initial purity of the accelerated state. However, the
larger values of the white noise strength improve the generated entanglement.
The initial parameters that describe this system are estimated by using Fisher
information, where two forms are considered, namely by using a single and
two-qubit forms. It is shown that, by using the two-qubit form, the estimation
degree of these parameters is larger than that displayed by using a
single-qubit form.
