The electron–hole correlation effects on the energy levels and the wave functions of a strain‐induced quantum dot containing 1 to 10 electron–hole pairs have been studied using large scale configuration‐interaction calculations. The results show the importance of including the correlations in order to reproduce the experimentally measured quantum dot spectra and to obtain bound multi‐exciton complexes. Increasing the number of electron–hole pairs in the quantum dot a transition from a strongly correlated system to the one approximated by the Hartree‐Fock theory is observed.
