iSense: A Portable Ultracold-Atom-Based Gravimeter

We present iSense, a recently initiated FET project aiming to use Information and Communication Technologies (ICT) to develop a platform for portable quantum sensors based on cold atoms. A prototype of backpack-size highprecision force sensor will be built to demonstrate the concept. © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.

Raman laser system and radio frequency experiments for driving two-photon transitions in 87Rb

This report presents two approaches for driving two-photon transitions between hyperfine states in the Rb ground state. These hyperfine states are intended for use as qubit states in quantum information processing with neutral atoms. The first approach uses microwave and radio frequency fields, and experiments on microwave singleand two-photon transitions showing the magnetically dependent Zeem...

Influence of lasers propagation delay on the sensitivity of atom interferometers

In atom interferometers based on two photon transitions, the delay induced by the difference of the laser beams paths makes the interferometer sensitive to the fluctuations of the frequency of the lasers. We first study, in the general case, how the laser frequency noise affects the performance of the interferometer measurement. Our calculations are compared with the measurements performed on o...

Generating controllable atom-light entanglement with a Raman atom laser system.

We introduce a scheme for creating continuous variable entanglement between an atomic beam and an optical field, by using squeezed light to outcouple atoms from a Bose-Einstein condensate via a Raman transition. We model the full multimode dynamics of the atom laser beam and the squeezed optical field and show that, with appropriate two-photon detuning and two-photon Rabi frequency, the transmi...
