Submission + - Harvard Physicists Bring Light to a Complete Halt

tetrikphimvin writes: "In a quantum mechanical sleight of hand, Harvard physicists have shown that they can not only bring a pulse of light, the fleetest of nature's particles, to a complete halt, but also resuscitate the light at a different location and let it continue on its way.
"It's been a wonderful problem to try to wrap your brain around," said Lene Vestergaard Hau, a professor of physics at Harvard and senior author of a paper describing the experiment that appears today in the journal Nature. "There are so many doors that open up." This is also noted in Harvard's Gazette here, which includes video links."
