Single and coupled multiple quantum-dot structures have long been proposed as systems for storing and manipulating information in quantum information processing. However, finding routes to get the coupled dots to communicate are only now being explored. Stinaff et al. (p. 636, published online 12 January) present a spectroscopic study of pairs of neutral and charged quantum dots where coherent coupling between the dots can be induced by a combination of electric field resonances and optical excitation. The main spectroscopic features can be recovered with a relatively simple molecular model.
