Spintronics approach enables new quantum technologies
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.

Atom by Atom, Bond by Bond, a Chemical Reaction Caught in the Act
The single-atom tip of the noncontact atomic force microscope “feels” changes in the strength of electronic forces as it moves across the surface at a constant height. Resulting movements of the stylus are detected by a laser beam to compute images.
