Coherent Quantum State Manipulation of Trapped Atomic Ions

January 1, 1998
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, laser-cooled, trapped 9Be+ ion is used to investigate methods of coherent quantum-state synthesis. We create and characterize nonclassical states of motion including "Schrödinger- cat" states. A fundamental quantum logic gate is realized using

Minimization of ion micromotion in a Paul trap

January 1, 1998
Author(s)
D J. Berkeland, J D. Miller, James C. Bergquist, Wayne M. Itano, David J. Wineland
Micromotion of ions in Paul traps has several adverse effects, including alterations of atomic transition line shapes, significatn second-order Doppler shifts in high-accuracy studies and limited confinement time in the absence of cooling. The ac electric

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
