The phonon-induced dephasing dynamics in optically excited semiconductor
quantum dots is studied within the frameworks of the independent Boson model
and optimal control. We show that appropriate tailoring of laser pulses allows
a complete control of the optical excitation despite the phonon dephasing, a
finding in marked contrast to other environment couplings.
