Quantum jump photodetector for narrowband photon counting with a single atom Open
Using a single neutral Rb87 atom held in an optical trap, and “quantum jump” detection of single-photon-initiated state changes, we demonstrate a single-photon quantum jump photodetector (QJPD) with intrinsically narrow bandwidth and stron…

Quantum jump spectroscopy of a single neutral atom for precise subwavelength intensity measurements Open
We present precise, subwavelength optical intensity measurements using a single trapped ^{87}Rb atom as a sensor. The intensity is measured by the scalar ac Stark shift it produces on the F=1→F^{′}=2 hyperfine transition of the D_{2} line,…
