A Coaxial-Resonator Driven rf(Paul)-Trap for Strong Confinement

January 1, 1995
Author(s)
Steven R. Jefferts, C Monroe, E W. Bell, David J. Wineland
We describe a variant of the quadrupole rf (Paul) ion trap capable of localization of a trapped ion to much less than an optical wavelength (Lamb-Dicke regime). The trapping potentials are generated by a high-Q, vacuum-compatible, quarter-wave resonator

Demonstration of a Fundamental Universal Quantum Logic Gate

January 1, 1995
Author(s)
C Monroe, D M. Meekhof, B E. King, Wayne M. Itano, David J. Wineland
We demonstrate the operation of a two-bit "controlled-NOT" quantum logic gate, which, in conjunction with simple single-bit operations, forms a universal quantum logic gate for quantum computation. The two quantum bits are stored in the internal and

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

January 1, 1995
Author(s)
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

January 1, 1993
Author(s)
Wayne M. Itano, James C. Bergquist, John J. Bollinger, J M. Gilligan, D J. Heinzen, F L. Moore, M G. Raizen, David J. Wineland
