Quantum Information splitting using a pair of GHZ states
Kaushik Nandi, Goutam Paul
We describe a protocol for quantum information splitting (QIS) of a restricted class of three-qubit states among three parties Alice, Bob and Charlie, using a pair of GHZ states as…
Feedback control of trapped coherent atomic ensembles
T. Vanderbruggen, R. Kohlhaas, A. Bertoldi +4
We demonstrate how to use feedback to control the internal states of trapped coherent ensembles of two-level atoms, and to protect a superposition state against the decoherence ind…
Transport regimes of cold gases in a two-dimensional anisotropic disorder
L. Pezze, M. Robert-de-Saint-Vincent, T. Bourdel +6
We numerically study the dynamics of cold atoms in a two-dimensional disordered potential. We consider an anisotropic speckle potential and focus on the classical regime, which is…
Anisotropic 2D diffusive expansion of ultra-cold atoms in a disordered potential
M. Robert-de-Saint-Vincent, J. -P. Brantut, B. Allard +6
We study the horizontal expansion of vertically confined ultra-cold atoms in the presence of disorder. Vertical confinement allows us to realize a situation with a few coupled harm…
Anderson Localization of Bogolyubov Quasiparticles in Interacting Bose-Einstein Condensates
Pierre Lugan, David Clément, Philippe Bouyer +2
We study the Anderson localization of Bogolyubov quasiparticles in an interacting Bose-Einstein condensate (with healing length ξ) subjected to a random potential (with finite corr…
Coherent matter wave inertial sensors for precision measurements in space
Yann Le Coq, Jocelyn A. Retter, Simon Richard +2
We analyze the advantages of using ultra-cold coherent sources of atoms for matter-wave interferometry in space. We present a proof-of-principle experiment that is based on an anal…
