Atomic Physics in Ion Traps

March 1, 1997
Author(s)
C Monroe, John Bollinger
Ion traps allow researchers to control the position and movement of charged particles with exquisite precision, and provide a powerful way to study many atomic phenomena.

Optimal Frequency Measurements with Maximally Correlated States

December 1, 1996
Author(s)
John J. Bollinger, Wayne M. Itano, David J. Wineland, D J. Heinzen
We show how maximally correlated states of N two-level particles can be used in spectroscopy to yield a frequency uncertainty equal to (NT)-1, where T is the time of a single measurement. From the time-energy uncertainty relation we show that this is the

Entangled States of Atomic Ions for Quantum Metrology and Computation

January 1, 1996
Author(s)
David J. Wineland, C Monroe, D M. Meekhof, B E. King, Dietrich G. Leibfried, Wayne M. Itano, James C. Bergquist, D J. Berkeland, John J. Bollinger, J D. Miller
A single trapped 9Be+ ion is used to investigate Jaynes-Cummings dynamics for a two-level atomic system coupled to harmonic atomic motion. We create and investigate nonclassical states of motion including "Schrödinger-cat" states. A fundamental quantum

Experiments at NIST with Trapped Ions: 3-D Zero-Point Cooling, Quantum Gates, Bragg Scattering, and Atomic Clocks

June 12, 1995
Author(s)
C Monroe, A S. Barton, James C. Bergquist, D J. Berkeland, John Bollinger, F C. Cruz, Wayne M. Itano, Steven R. Jefferts, Branislav M. Jelenkovic, B E. King, D M. Meekhof, J D. Miller, M E. Poitzsch, Joseph N. Tan
We have recently used stimulated-Raman transitions in the resolved sideband regime to cool single ions to the n = 0 zero-point energy. This has allowed realizations of the Jaynes-Cummings model interaction for atomic motion and a quantum controlled-NOT

Squeezed Atomic States and Projection Noise in Spectroscopy,

January 1, 1994
Author(s)
David J. Wineland, John J. Bollinger, Wayne M. Itano, D J. Heinzen
We investigate the properties of angular-momentum states which yield high sensitivity to rotation. We discuss the application of these "squeezed-spin" or correlated-particle states to spectroscopy.
