Heating of trapped ions from the quantum ground state

Autor: Turchette, Q. A., Kielpinski, D., King, B. E., Leibfried, D., Meekhof, D. M., Myatt, C. J., Rowe, M. A., Sackett, C. A., Wood, C. S., Itano, W. M., Monroe, C., Wineland, D. J.

We have investigated motional heating of laser-cooled 9Be+ ions held in radio-frequency (Paul) traps. We have measured heating rates in a variety of traps with different geometries, electrode materials, and characteristic sizes. The results show that

Experimental issues in coherent quantum-state manipulation of trapped atomic ions

Autor: Wineland, D. J., Monroe, C., Itano, W. M., Leibfried, D., King, B. E., Meekhof, D. M.

Publikováno v: J.Res.Natl.Inst.Stand.Tech. 103 (1998) 259

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 lo

Quantum state manipulation of trapped atomic ions

Autor: Wineland, D. J., Monroe, C., Meekhof, D. M., King, B. E., Leibfried, D., Itano, W. M., Bergquist, J. C., Berkeland, D., Bollinger, J. J., Miller, J.

A single laser-cooled and trapped 9Be+ ion is used to investigate methods of coherent quantum-state synthesis and quantum logic. We create and characterize nonclassical states of motion including "Schroedinger-cat" states. A fundamental quantum logic

Quantum harmonic oscillator state synthesis and analysis

Autor: Itano, W. M., Monroe, C., Meekhof, D. M., Leibfried, D., King, B. E., Wineland, D. J.

Experiments are described in which a single, harmonically bound, beryllium ion in a Paul trap is put into Fock, thermal, coherent, squeezed, and Schroedinger cat states. Experimental determinations of the density matrix and the Wigner function are de

Simplified quantum logic with trapped ions

Autor: Monroe, C., Leibfried, D., King, B. E., Meekhof, D. M., Itano, W. M., Wineland, D. J.

We describe a simplified scheme for quantum logic with a collection of laser-cooled trapped atomic ions. Building on the scheme of Cirac and Zoller, we show how the fundamental controlled-NOT gate between a collective mode of ion motion and the inter
