This breakthrough could lead to the creation of long-range quantum networks.
University of Darmstadt scientists in Germany have stopped light for one minute. Light is usually the fastest thing in the known universe and travels at 300 million meters per second, but was stopped dead still inside a crystal for one full minute. This effectively creates light memory, where the image being carried by the light is stored in crystals. Beyond being utterly cool, this breakthrough could lead to the creation of long-range quantum networks — and perhaps, tantalizingly, this research might also give us some clues on accelerating light beyond the universal speed limit.
