One step closer to quantum computing
PRINCETON (US)—Physicist Jason Petta may have overcome a major hurdle to designing and constructing a radically new kind of quantum computer. He’s figured out how to manipulate the single electrons that very likely will constitute the new machines’ processing components or “qubits.” (more…)
