Query: Decoherence effects on the generation of exciton entangled states in
  coupled quantum dots   We report on exciton-acoustic-phonon coupling effects on the generation of
exciton maximally entangled states in N=2 and 3 quantum dot systems. In
particular, we address the question of the combined effect of laser pulses,
appropriate for generating Bell and Greenberger-Horne-Zeilinger entangled
states, together with decoherence mechanisms as provided by a phonon reservoir.
By solving numerically the master equation for the optically driven
exciton-phonon kinetics, we show that the generation of maximally entangled
exciton states is preserved over a reasonable parameter window.
