Resolved-Sideband Raman Cooling of a Bound Atom to the 3D Zero-Point Energy

January 1, 1995

C Monroe, D M. Meekhof, B E. King, Steven R. Jefferts, Wayne M. Itano, David J. Wineland, P Gould
We report laser cooling of a single 9Be+ ion held in a rf (Paul) ion trap to where it occupies the quantum-mechanical ground state of motion. With the use of resolved-sideband stimulated Raman cooling, the zero point of motion is achieved 98% of the time

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.

Quantum Measurements of Trapped Ions

Quantum Projection Noise: Population Fluctuations in 2-Level Systems

January 1, 1993

Wayne M. Itano, James C. Bergquist, John J. Bollinger, J M. Gilligan, D J. Heinzen, F L. Moore, M G. Raizen, David J. Wineland
Measurements of internal energy states of atomic ions confined in traps can be used to illustrate fundamental properties of quantum systems, because long relaxation times and observation times are available. In the experiments described here, a single ion
