In a two-mode Bose-Josephson junction the dynamics induced by a sudden quench of the
tunnel amplitude leads to the periodic formation of entangled states. For instance, squeezed …

Laser-cooled atoms offer an excellent platform for testing new ideas of quantum control and
measurement. I will discuss experiments where we use light and magnetic fields to drive and …

Ce manuscrit décrit l'étude et le développement de capteurs inertiels fondés sur l'utilisation
de l'interférométrie atomique. Une introduction historique du domaine est suivie d'une …

In this thesis, I present the motivation and design for an experiment in which to probe the
interactions between an atom and a single photon light field. I discuss the relevant technical …

Ultimate quantum fluctuations which limit the fundamental precision in metrology can be
only reduced by entanglement of particles. In particular, squeezing of the fluctuations called …

Spin squeezing, the generation of collective states of atomic ensembles with reduced spin
noise by exploiting non-classical correlations between particles, is a promising approach to …
