Slow down: John Howell has so far been able to delay light pulses by 100 ns and compress them to 1% of their original length. He is now working toward delaying dozens of pulses for as long as several milliseconds, and as many as 10,000 pulses for up to 1 ns. "Now I want to see if we can delay something almost permanently, even at the single photon level," said Howell. "If we can do that, we're looking at storing incredible amounts of information in just a few photons." |
