All-Optical Control of Electron Spin

Caption: This artist's rendering shows all-optical control of an individual electronic spin within a diamond. This spin is associated with a naturally occurring defect in diamond known as the nitrogen-vacancy center, a promising quantum bit (qubit) for quantum information processing. The University of Chicago's David Awschalom and his associates have developed techniques to initialize, manipulate, and read out the electronic spin of this qubit using only pulses of light.
