Training Foundation Models with a Single Algorithm
Yuda Song, Alvin Zhang, Fahim Tajwar +7
Foundation models are typically trained in stages: pretraining, midtraining, supervised fine-tuning (SFT), and reinforcement learning (RL), with changes in both data and learning a…
Quantum sensing of radiofrequency fields using cold Rydberg atoms in a super-molasses trap
Romain Granier, Anthony El Bekai, Miguel Angel Cifuentes Marín +12
We demonstrate the quantum sensing of radiofrequency fields based on cold Rydberg atoms in a super-molasses trap, without the need for magnetic coils. Our approach combines the met…
Characterisation of a triple-species 87Rb/85Rb/133Cs magneto-optical trap towards cold-atom interferometry
Mal Landru, Amandine Lauret, Yannick Bidel +5
We present the simultaneous trapping and cooling of Rb, Rb and Cs in a triple-species magneto-optical trap (MOT). This demonstration is obtained using a…
Rydberg Receivers for Space Applications
Gianluca Allinson, Mark Bason, Alexis Bonnin +10
Rydberg-atom sensors convert radiofrequency, microwave and terahertz fields into optical signals with SI-traceable calibration, high sensitivity, and broad tunability. This review…
Impact of rotation on a cold atom interferometer and compensation strategy
Noémie Marquet, Yannick Bidel, Malo Cadoret +8
Rotations play a detrimental role in achieving ultra-high-performance inertial measurements with an atom interferometer, leading potentially to a total loss of interference contras…
Quantum sensing of acceleration and rotation by interfering magnetically-launched atoms
Clément Salducci, Yannick Bidel, Malo Cadoret +6
Accurate measurement of inertial quantities is essential in geophysics, geodesy, fundamental physics and navigation. For instance, inertial navigation systems require stable inerti…
Metrology of microwave fields based on trap-loss spectroscopy with cold Rydberg atoms
Romain Duverger, Alexis Bonnin, Romain Granier +7
We demonstrate a new approach for the metrology of microwave fields based on the trap-loss-spectroscopy of cold Rydberg atoms in a magneto-optical trap. Compared to state-of-the-ar…
Experimental study of the role of trap symmetry in an atom-chip interferometer above the Bose-Einstein condensation threshold
Matthieu Dupont-Nivet, Romain Demur, Christoph I. Westbrook +1
We report the experimental study of an atom-chip interferometer using ultracold rubidium 87 atoms above the Bose-Einstein condensation threshold. The observed dependence of the con…
