  • Today, if a submarine goes a day without a GPS fix they'll have a navigation drift of the order of a kilometer when it surfaces, says Neil Stansfield at the UK Defence Science and Technology Laboratory at Porton Down. A quantum accelerometer will reduce that to just 1 meter. To create the supersensitive quantum accelerometers, Stansfield's team was inspired by the Nobel-prizewinning discovery that lasers can trap and cool a cloud of atoms placed in a vacuum to a fraction of a degree above absolute zero.
