Quantum Computing with Neutral Atoms in an Optical Lattice

We present a proposal for quantum information processing with neutral atoms trapped in optical lattices as qubits. Initialization and coherent control of single qubits can be achieved with standard laser cooling and spectroscopic techniques. We consider entangling two-qubit logic gates based on optically induced dipole-dipole interactions, calculating a figure-of-merit for various protocols. Ma...

Long-distance quantum communication with neutral atoms

In this thesis, we develop quantitative performance analyses for a variety of quantum communication/computation systems that have the common feature of employing neutral atoms for storage/processing and photons for qubit transmission. For most of these systems, there is a lack of a precise performance analysis to enable a comparison between different scenarios from a top-level system standpoint...

Quantum computing and quantum communication with atoms

We review recent theoretical proposals for implementation of quantum computing and quantum communication with atoms. The first example deals with the realization of a universal quantum simulator with atoms and ions. The second example outlines the implementation of a quantum repeater with atomic ensembles.
