Abstract A time‐dependent quantum adiabatic switching algorithm is exploited to determine the eigenstates of 2‐D quantum dots perturbed by a repulsive scatterer. Several forms of switching functions are explored and optimal forms are suggested. The switching paths are compared for a number of states, using overlap, information entropy and energy as descriptors for possible identification of the optimal switching function. © 2007 Wiley Periodicals, Inc.
