Fast, powerful, low-noise optical pumping of an atomic vapor with semiconductor optical amplifiers
Diana Méndez-Avalos, Théo Louzada Meireles, Morgan W. Mitchell +1
We use a atomic vapor, suitable for an optically-pumped magnetometer (OPM) in Earth-field conditions, to study the noise properties of three strategies for generat…

Quantum noise scaling in continuously operating multiparameter sensors
Aleksandra Sierant, Diana Méndez-Avalos, Santiago Tabares Giraldo +1
We experimentally investigate the quantum noise mechanisms that limit continuously operating multiparameter quantum sensors. Using a hybrid rf-dc optically pumped magnetometer, we…
