Quantum dots may be small. But they usually don't let anyone push them around. Now, however, JQI Fellow Edo Waks and colleagues have devised a self-adjusting remote-control system that can place a dot 6 nanometers long to within 45 nm of any desired location. That's the equivalent of picking up golf balls around a living room and putting them on a coffee table - automatically, from 100 miles away.
