Single trapped ions represent elementary quantum systems that are well isolated from the
environment. They can be brought nearly to rest by laser cooling, and both their internal …

Quantum information processors exploit the quantum features of superposition and
entanglement for applications not possible in classical devices, offering the potential for …

Publisher Summary This chapter discusses optical dipole traps for neutral atoms. Methods
for storage and trapping of charged and neutral particles have very often served as the …

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 …

We report cooling of a single neutral atom to its three-dimensional vibrational ground state in
an optical tweezer. After employing Raman sideband cooling for tens of milliseconds, we …

Bose-Einstein condensation of cesium atoms is achieved by evaporative cooling using
optical trapping techniques. The ability to tune the interactions between the ultracold atoms …

We propose a new system for implementing quantum logic gates: neutral atoms trapped in a
very far-off-resonance optical lattice. Pairs of atoms are made to occupy the same well by …

A laser cooling method for trapped atoms is described which achieves ground state cooling
by exploiting quantum interference in a driven Λ-shaped arrangement of atomic levels. The …

We investigate quantum control of a single atom in a tightly focused optical tweezer trap. We
show that inevitable spatially varying polarization gives rise to significant internal-state …

We demonstrate a simple, general purpose method to cool neutral atoms. A sample
containing 3× 10 8 cesium atoms prepared in a magneto-optical trap is cooled and …
