The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated. The scientists used lasers to create an initialized quantum state of this solid-state qubit at rates of about a gigahertz, or a billion times per second. They can also use lasers to achieve fundamental steps toward programming it.
