Nobel physics prize highlights quantum optics
[ Tue, 9 Oct 2012 15:46:29 GMT ]

An illustration shows how an optical atomic clock developed at the National Institute of Standards and Technology uses two magnetic coils (red rings) and an optical lattice (red laser beam), as well as intersecting violet lasers to cool ytterbium atoms, slowing their motion. The principles of quantum optics help make atomic clocks more accurate.Frenchman Serge Haroche and American David Wineland have won the 2012 Nobel Prize in physics for inventing and developing methods for observing tiny quantum particles without destroying them.
