Ion Optical Clocks and Quantum Information Processing



David J. Wineland, James C. Bergquist, Till P. Rosenband, Piet Schmidt, Wayne M. Itano, John J. Bollinger, Dietrich G. Leibfried, W Oskay


We summarize experiments at NIST that (1) use guantum gates to entabgle ions and thereby improve the measurement signal-to-noise ratio in spectroscopy and (2) implement sympathetic cooling and quantum state transfer techniques, which might be used to increase the number of chices of ions used for clocks.
