We show that phonon‐induced pure dephasing of excitons in quantum dots, which leads only to partial decay of system coherence, may completely erase entanglement between two excitons. We also discuss the role of the distance between the subsystems for this disentanglement process. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
