Submicrometer position control of single trapped neutral atoms.
We optically detect the positions of single neutral cesium atoms stored in a standing wave dipole trap with a subwavelength resolution of 143 nm rms. The distance between two simultaneously trapped atoms is measured with an even higher precision of 36 nm rms. We resolve the discreteness of the interatomic distances due to the 532 nm spatial period of the standing wave potential and infer the ex...
متن کاملOptical control of single neutral atoms
This thesis presents experiments concerning the preparation and manipulation of single neutral atoms in optical traps. The experimental setup as well as the properties of the optical dipole trap are described. The long term goal of this experiment is to use trapped atoms as information carriers in quantum information processing. The examination and control of all trapping parameters and heating...
متن کاملQuantum Information Processing with Trapped Neutral Atoms
Quantum information can be processed using large ensembles of ultracold and trapped neutral atoms, building naturally on the techniques developed for high-precision spectroscopy and metrology. This article reviews some of the most important protocols for universal quantum logic with trapped neutrals, as well as the history and state-of-the-art of experimental work to implement these in the labo...
متن کاملLossless state detection of single neutral atoms.
We introduce lossless state detection of trapped neutral atoms based on cavity-enhanced fluorescence. In an experiment with a single 87Rb atom, a hyperfine-state-detection fidelity of 99.4% is achieved in 85 μs. The quantum bit is interrogated many hundreds of times without loss of the atom while a result is obtained in every readout attempt. The fidelity proves robust against atomic frequency...
متن کاملQuantum Control and Entanglement Engineering with Cold Trapped Atoms
Neutral atoms offer many advantages for quantum computation, including excellent isolation from the decohering environment and the existence of proven laboratory techniques for atom trapping and quantum control. Currently the most mature trapping technology is offered by optical lattices, arrays of microtraps formed by the AC Stark shift in laser standing waves, which provide an excellent platf...
