Outloo~ The research axis of the Group are strongly oriented towards the manipulation of individual objects or small sets ofobjects Possible applications of this work fall inside the fields of nanotechnologies and quantum information From a more fundamental point of view the group aims to produce strongly non-cassical states in a controlled way and to control their coupting the environ ment

trapping and manipulation by optical means The group is exploring ways to encode information on atoms and to perform between them the quantum equivalent ofusuallogical operations These activities enter the framework of the new field called Quantum Information) but cannot be reduced to this framework only From a more geneshylal point of view) the main goal of the group is to produce and manipulate matter and light states that do not have any cassical equivalent) and that alow an experimental approach to basic quantum mechanics questions such as measurement and non-Iocality

The atom optics group is working along several lines of research most of them analogous to traditional optics

~ Coherent atom optics We are studying atom lasers formed by the coherent outcoupling ofatoms (rom a Bose-Einstein condensate We are also interested in atom interferometry) a topic which as already been investigated with cold but not condensed atomic samples) and which may benefit from the use of atom lasers in the same way that optical interferometry has benefitted (rom the introduction ofthe laser One ofour aims is the miniaturisation ofthese devices and their application in space

~ Quantum atom optics Our group has a long experience in the manipulation of metastable helium In particular we can achieve single atom detection) a technique which has alloshywed us to implement counting technishyques similar to those which initiated modern quantum optics

~ Integrated atom optics Atom chips use the capabilities ofnanofashybrication technolo)l to realize the fugravencshytions of IInormal atom optics experiments on a silicon surface ofa few square millimeshyters rather than an entire room

We have produced a Bose-Einstein condensate on a chip which opens many new possibilities in the study of quanshytum degenerate gases especially in lower dimensions

Because of the central raIe of interatoshymic interactions and the very different behavior of bosons and fermions) the field ofatom optics is also at the fronshytier with condensed matter physics We are thus also studying degenerate gases in periodic or random potentials

The atom optics group has a large variety of experimental apparatus with the capability ofproducing condensates of rubidium and metastable helium as weil as Bose-Fermi mixtures of rubishydium and potassium Several different trapping configurations are available from cloverleaf and iron core magnetic traps to atom chips and optical tweeshyzers These setups cover a wide ranging program going from fundamental stushydies such as atom lasers) gases in ranshydom potentials and atom correlations to applications) particularly in the field of inertial and gravitational sensors) and quantum information processing We also have a smail theoretical team which works in close collaboration with the experimenters

Key words Ultra cold atoms degenerate quantum gases Bose-Einstein condensates atom lasers correloted atoms atom chips periodic and random potentials

Clmanipulate atoms the way you manipulate light in photonics

Our many external collaborations include our membership in IFRA~ a consortium of laboratories in the Paris area as weil other national and internashytional programs

A small part of the group is also doing research in biophotonics in collaborashytion with the Institut de Chimie des Substances Naturelles in Gifsur Yvette
