What a pair! Coupled quantum dots may offer a new way to store quantum information

Researchers have, for the first time, created and imaged a novel pair of quantum dots – tiny islands (100 nanometers in diameter) of confined electric charge that act like artificial atoms. Such a ''coupled'' quantum dot could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer.
