Trapping spins with sound

Color centers are lattice defects in crystals that can capture one or more additional electrons. The spin of these electrons is very sensitive to external electric and magnetic fields -- and to sound. Researchers are now reporting the selective manipulation of electron spins in both their ground and excited states with sound. Their approach opens the path to new methods for processing quantum information inaccessible so far.
