Time & frequency

Time and frequency activities at NIST include maintaining standards, providing official time to the U.S., and carrying out a broad program of research and service activities in time and frequency metrology.

NIST and the Nobel: Dave Wineland

NIST physicist David J. Wineland received the 2012 Nobel Prize in Physics "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems."

In a closely related line of research, Wineland and the members of his laboratory group have used laser-cooled ions to build new, ultra-precise atomic clocks, several of which have held the world record for accuracy. Laser-cooled clocks now set primary time and frequency standards around the world.
