Current inquiry explores the time-dependent quantum adiabatic switching (TDQAS) of impurity doped quantum dot (QD) under the aegis of Gaussian white noise (GWN). The QAS has been performed among the impurity modulated states of QD using several switching functions (SFs). The time-evolution of switching has been monitored with the help of overlap function and quantum information entropy (QIE). The SFs appear to recover the impurity-modulated eigenstates of QD corresponding to the final Hamiltonian starting from the analogous QD eigenstates corresponding to the initial Hamiltonian. The switching paths have been found to be comprising of important physical attributes of overlap function and QIE. These subtleties of the switching paths and the efficiency of switching/recovery depend on the nature of the SF itself and the characteristics of noise. The study deems importance since impurities have become inalienable part of QD systems for immense technological applications where presence of noise could invite additional delicacies.
