摘要：
The degree of entanglement of an electron with a hole in a vertically coupled self-assembled dot molecule is shown to be tunable by an external electric field. Using atomistic pseudopotential calculations followed by a configuration interaction many-body treatment of correlations, we calculate the electronic states, degree of entanglement, and optical absorption. We offer a way to spectroscopically detect the magnitude of electric field needed to maximize the entanglement.
