Semiconductor quantum dots (QDs) are typically entirely uncoupled, and interfacial QDs are no exception. However, exciting higher-energy quantum-well states can turn on QD interactions. Here, the authors measure individual QDs with a coherent spectroscopy that is extremely sensitive to interactions. They demonstrate an induced binding between two distinct QDs with a very weak excitation of delocalized quantum-well states. This interaction is presented as a possible method for turning on coupling between quantum states and for measuring fundamental processes in semiconductors with nanometer spatial resolution.
