Abstract

Pure dephasing of two electrons in vertically coupled quantum dots due to the interaction with acoustic and optical phonons is calculated. We study the effect of pure dephasing on the entanglement of the two-level subsystems. Our results show the role of the size and the distance between the two quantum dots on the pure dephasing rates.
