Sensors based on quantum-effects in atoms have seen rapid transitions from proof-of-principle experiments to commercial devices. Quantum atomic magnetometers based on alkali vapor cells benefit from high sensitivities combined with simple optical set

An array of 21 first-order gradiometers based on zero-field optically-pumped magnetometers is demonstrated for use in magnetoencephalography. Sensors are oriented radially with respect to the head and housed in a helmet with moveable holders which co

Optically pumped magnetometers (OPMs) operating in the spin-exchange relaxation-free regime are emerging as alternative sensors to superconducting quantum interference devices (SQUIDs) for magnetoencephalography (MEG). As the number of OPMs in a sing

We present on our ongoing development of microfabricated optically-pumped magnetometer (OPM) arrays for magnetic field imaging applications, spanning size scales from tens of microns to kilometres. At the heart of the OPMs are microfabricated rubidiu

We demonstrate electromagnetically induced transparency with the control laser in a Laguerre–Gaussian mode. The transmission spectrum is studied in an ultracold gas for the D2 line in both 85Rb and 87Rb, where the decoherence due to diffusion of th

We present an experimental noise characterization of a miniature single-beam absorption-based optically-pumped magnetometer with a noise floor of 7 fT/Hz(1/2) operating in the spin-exchange relaxation-free regime. We experimentally evaluate noise ari

We demonstrate Feshbach optimized photoassociation (FOPA) into the ${0}_{g}^{\ensuremath{-}}(5{S}_{1/2}+5{P}_{1/2})$ state in $^{85}\mathrm{Rb}_{2}$. FOPA uses the enhancement of the amplitude of the initial atomic scattering wave function due to a F
