We describe the operation of a light pulse interferometer using cold 87 Rb atoms in reduced
gravity. Using a series of two Raman transitions induced by light pulses, we have obtained …

We propose a compact and robust laser system at 780 nm for onboard atomic inertial
sensors based on rubidium atom interferometry. The principle of this system consists in …

We propose a scheme for testing the weak equivalence principle (universality of free-fall
(UFF)) using an atom-interferometric measurement of the local differential acceleration …

A typical atom interferometer requires vastly different laser frequencies at different stages of
operation, eg, near resonant light for laser cooling and far detuned light for atom optics, such …

Ce manuscrit présente une série d'expériences réalisées sur des atomes de Rubidium
piégés et refroidis grâce à des forces induites par laser. Lorsque le laser est très désaccordé …

Technical progress in both industry and science has enabled the preparation, manipulation,
and probing of quantum systems with an unprecedented level of control. This provides the …

In this thesis, we report on the study of atomic sources for long-time-of-flight inertial sensing,
as well as the experimental realization of two of such sources. First, we show that the …

La conception et la réalisation d'un gravimètre à atomes froids embarquable sont
présentées. L'utilisation d'un tel instrument peut permettre de mesurer de façon précise et …

Quantum computers are expected to efficiently solve optimization problems occurring in
logistics or urban development and to enable computation-intensive simulations required for …

La gravitation expérimentale a connu des développements spectaculaires ces vingt
dernières années en partie grâce aux développements de la physique atomique. A l'aide de …
