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

Experimental Issues in Coherent Quantum-State Manipulation of Trapped Atomic Ions,

January 1, 1998
Author(s)
David J. Wineland, C Monroe, Wayne M. Itano, Dietrich G. Leibfried, B E. King, D M. Meekhof
Methods for, and limitations to, the generation of entangled states of trapped atomic ions are examined. As much as possible, state manipulations are described in terms of quantum logic operations since the conditional dynamics implicit in quantum logic is

Experimental Primer on the Trapped Ion Quantum Computer,

January 1, 1998
Author(s)
David J. Wineland, C Monroe, Wayne M. Itano, B E. King, Dietrich G. Leibfried, D M. Meekhof, C J. Myatt, Chris S. Wood
The development of a quantum computer based on a system of trapped atomic ions is described, following the proposal of Cirac and Zoller. Initial results on a two-bit quantum logic gate are presented, and select experimental issues in scaling the system to

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

Quantum Logic with a Few Trapped Ions

January 1, 1998
Author(s)
C Monroe, Wayne M. Itano, D Kielpinski, B E. King, Dietrich Leibfried, C J. Myatt, Q A. Turchette, David J. Wineland, Chris S. Wood
Small laser-cooled crystals of atomic ions have attracted considerable interest in the last several years for their possible application toward quantum computation. This paper considers quantum logic schemes for small numbers of ions in the context of

Trapped Ions, Entanglement, and Quantum Computing, ed. by B.L. Fearey

January 1, 1998
Author(s)
C J. Myatt, B E. King, D Kielpinski, Dietrich Leibfried, Q A. Turchette, Chris S. Wood, Wayne M. Itano, C Monroe, David J. Wineland
A miniature, elliptcal ring rf (Paul) ion trap has been used in recent experiments toward realizing a quantum computer in a trapped ion system. With the combination of small spatial dimensions and high rf drive potentials, around 500 V amplitude, we have
