subbiesrock Posted December 28, 2010 Report Posted December 28, 2010 An article I was reading stated this interesting fact about advances in atomic clocks that I thought the horologically minded might like. A single ion tells time A single aluminum ion, vibrating a quadrillion times a second, is the basis for a new “quantum logic” clock developed by the National Institute of Standards and Technology. A prototype of the clock remains accurate to within a second every 3.7 billion years—significantly better than the current U.S. civilian time standard, a cesium fountain clock accurate to within a second every 100 million years. The General Conference on Weights and Measures, based in France, may consider the design for a new international time standard. Such precise clocks are used to synchronize telecommunications networks and deep-space communications and to assist satellite navigation and positioning. They could also lead to new types of space-based gravity sensors, used to locate underground natural resources.
