TL;DR: A review of various approaches to the implementation of quantum memories, with an emphasis on activities within the quantum memory sub-project of the EU integrated project “Qubit Applications”, is presented in this article.

TL;DR: The effective potential was measured for various condensate densities and trap geometries, yielding good qualitative agreement with theoretical calculations.

TL;DR: In this paper, experimental results on the properties of Bose-Einstein condensates in one-dimensional optical lattices were reported, and the dependence of the LZ tunneling rate on the condensate density was then related to mean-field effects modifying the effective potential acting on the Condensate, yielding good agreement with recent theoretical work.

TL;DR: In this article, the authors studied the diffraction of a released sodium Bose-Einstein condensate by a pulsed standing light wave and found that the width of the momentum distribution of diffracted atoms exhibits strong oscillations as a function of the pulse duration.

TL;DR: This work presents the first experimental realization of coherent Bragg scattering off a one-dimensional system-two strings of atoms strongly coupled to a single photonic mode-realized by trapping atoms in the evanescent field of a tapered optical fiber, which also guides the probe light.
