Abstract

Atomic clocks are the most precise timekeepers ever built. If you could keep an advanced atomic clock running long enough, it would neither gain nor lose a single second over the entire lifespan of the universe. With the availability of spectrally pure lasers and the ability to precisely measure optical frequencies, it appears the era of optical atomic clocks has begun. Advances in atomic clocks are expected to be important in a range of emerging technological applications, including quantum computers. Dr. David Wineland, 2012 Nobel Laureate in Physics, will explore the theoretical and technological know-how needed to build these ultra-precise timepieces during his Perimeter Institute Public Lecture on Wednesday, Nov. 4.
