What was discovered

Slow light is the propagation of an optical pulse at a very low group velocity, achieved through electromagnetically induced transparency in atoms, first usefully demonstrated by Stephen Harris and collaborators.

What it led to

  • optical storage of information (quantum memories)
  • advances in optical communications and quantum computing
  • studies of electromagnetically induced transparency
  • extreme reductions of light speed in the laboratory
