Abstract
Controllable interactions that couple quantum dots are a key requirement in the search for scalable solid state implementations for quantum information technology. From optical studies of excitons and corresponding calculations, we demonstrate that an electric field on vertically coupled pairs of quantum dots controls the mixing of the exciton states on the two dots and also provides controllable coupling between carriers in the dots.
