A single-electron transistor with a central component -- an island only 1.5 nanometers in diameter -- that operates with the addition of only one or two electrons has been developed. The transistor, named SketchSET, provides a building block for new, more powerful computer memories, advanced electronic materials, and the basic components of quantum computers that could solve problems so complex that all of the world's computers working together for billions of years could not crack them.
