Laser-written micro-channel atomic magnetometer
Andrea Zanoni, Kostas Mouloudakis, Michael C. D. Tayler +4
We demonstrate a sensitive optically-pumped magnetometer using rubidium vapor and 0.75 amg of nitrogen buffer gas in a sub-mm-width sensing channel excavated by femtosecond laser w…

Quantum jump photodetector for narrowband photon counting with a single atom
Laura Zarraoa, Romain Veyron, Tomas Lamich +2
Using a single neutral 87Rb atom held in an optical trap, and "quantum jump" detection of single-photon-initiated state changes, we demonstrate a single-photon quantum jump photode…
