This issue's cover picture refers to the Feature Article by Coish and Baugh on pages 2203–2215. The authors review recent theoretical and experimental advances toward understanding the effects of nuclear spins in confined nanostructures. These systems, which include quantum dots, defect centers, and molecular magnets, are particularly interesting for their importance in quantum information processing devices, which aim to coherently manipulate single electron spins with high precision. The illustration shows an electron confined to a gated lateral quantum dot. The electron envelope function is represented by a translucent blue sphere. An electron spin (large blue arrow) interacts with many nuclei at atomic sites (red and blue spheres), which typically carry a finite spin (represented by small yellow arrows).
