IN 2016 a British submarine will slip its moorings and set sail under the guidance of the quantum world. The navigation system it will be testing should record the vessel's position with 1000 times more accuracy than anything before.
If successful, the system, known as quantum positioning, could be miniaturised for use in aircraft, trains, cars and even cellphones. This would provide a backup navigation tool in cities' concrete canyons, or in autonomous vehicles, where a loss of GPS signal can be dangerous.
