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…
Comparison and optimisation of hybridization algorithms for onboard classical and quantum accelerometers
Benoit Kaczmarczuk, Yannick Bidel, Alexandre Bresson +6
We study two hybridization algorithms used for the combination of a quantum inertial sensor based on atom interferometry with a classical inertial sensor for onboard acceleration m…
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…
