The Time and Frequency Division, part of the NIST Physical Measurement Laboratory, maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology.
2012 Nobel Prize in Physics to Dave Wineland of NIST Time and Frequency Division
Dave Wineland, Leader of the Ion Storage Group, shares the 2012 Nobel Prize in Physics with Serge Haroche of France "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems." Dave and his colleagues use these techniques for research in quantum information processing, quantum simulation, atomic clocks, and other areas.
