Quantum computing leap forward: altering a lone electron without disturbing its neighbors

Quantum computing leap forward: altering a lone electron without disturbing its neighbors: "A major hurdle in the ambitious quest to design and construct a radically new kind of quantum computer has been finding a way to manipulate the single electrons that very likely will constitute the new machines' processing components or 'qubits.' Now, a physicist has discovered how to do just that -- demonstrating a method that alters the properties of a lone electron without disturbing the trillions of electrons in its immediate surroundings. The feat is essential to the development of future varieties of superfast computers with near-limitless capacities for data."
