TīmeklisLamb-Dicke perturbation theory in terms of final tem-peratures and cooling rates. Beyond the Lamb-Dicke limit, this characterization becomes unsuitable: on the one hand, the vibrational degrees of freedom are not strictly thermal and, on the other hand, the decay pro-cess does not follow a single exponential. Instead, the TīmeklisLamb-Dicke limit, sympathetic cooling and laser cooling using electromagnetically induced trans-parency. After that we discuss the problem of state detection using the electron shelving method. Then quantum gates are described. We introduce single-qubit rotations, two-qubit controlled-NOT and multi-qubit controlled-NOT gates.

Tīmeklis1998. gada 7. dec. · We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is shown to work analogously to sideband cooling of a single ion. Outside the Lamb-Dicke regime, the incommensurable frequencies of the two vibrational modes …
