21. Realization of a Quantum Random Walk With Ultracold Atoms
Published: 2/1/2004
Authors: D Ciampini, M B d'Arcy, J M Grossman, Kristian Helmerson, Paul D Lett, William D Phillips, A Vaziri, S L Rolston
Abstract: Classical random walks have many applications in computer science. Quantum random walks (QRWs) [1] have been suggested as the potential basis for quantum computing algorithms. Such algorithms have been reported, some of which offer an exponential spe ...

22. Superfluid-to-Mott-Insulating Transition in a One-Dimensional Atomic Gas
Published: 2/1/2004
Authors: C Fertig, K M O'Hara, J H Huckans, James V Porto, William D Phillips
Abstract: Over the past two decades, the Mott-insulating phase transition has received a great deal of attention as a prototypical example of a quantum phase transition in a strongly-correlated system for which quantum fluctuations drive the phase transition a ...

25. Optical Manipulation of Atoms at the Nanoscale
Published: 8/11/2003
Author: William D Phillips
Abstract: These notes are to provide an outline of a lecture presented at the Enrico Fermi Summer School at Nanoscale Science, held in Varenna in July 2000. They are not intended as a complete account of that lecture, but as an indication of the topics covere ...

26. Quantum Information With Neutral Atoms as Qubits
Published: 7/1/2003
Authors: James V Porto, S L. Rolston, B L Tolra, Carl J Williams, William D Phillips
Abstract: Neutral atoms trapped in periodic optical potentials (optical lattices) offer a possible route toward quantum computation. The atoms can be kept well isolated from the environment, yet can be easily manipulated with the tools of atomic physics. Thi ...

27. Quantum Information With Neutral Atoms as Quibits
Published: 7/1/2003
Authors: James V Porto, S L. Rolston, B L Tolra, Carl J Williams, William D Phillips
Abstract: One of the essential features of a quantum computer is a quantum register of well-characterized qubits. Neural atoms in optical lattices are a natural candidate for such a register. We have demonstrated a pattern loading technique that can be used ...

28. Patterned Loading of a Bose-Einstein Condensate Into an Optical Lattice
Published: 5/1/2003
Authors: S P Peil, James V Porto, B L Tolra, J Obrecht, B E. King, M Subbotin, S L. Rolston, William D Phillips
Abstract: We have developed a technique to control the placement of atoms in an optical lattice by using a superlattice comprising two separately manipulated, periodic optical potentials with commensurate periods. We demonstrate selective loading of Bose-cond ...
