A single atom emitting resonance fluorescence into a coherent beam, and its use for non-destructive atom thermometry
Tomáš Lamich, Laura Zarraoa, Sondos Elsehimy +2
Using a far-off-resonance optical dipole trap, we place a single neutral Rb atom in a weak, atom-resonant coherent beam, while also strongly illuminating it from an orthogon…
Detection of photon-level signals embedded in sunlight with an atomic photodetector
Laura Zarraoa, Tomas Lamich, Sondos Elsehimy +2
The detection of few-photon signals in a broadband background is an extreme challenge for photon counting, requiring filtering that accepts a narrow range of optical frequencies wh…
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…
Precise, super-resolving intensity measurement by quantum jump spectroscopy of a single neutral atom
Lorena C. Bianchet, Natalia Alves, Laura Zarraoa +3
We present precise, sub-wavelength optical intensity measurement using a single trapped Rb atom as a sensor. The intensity is measured by the scalar ac Stark shift it produc…
Manipulating and measuring single atoms in the Maltese cross geometry
Lorena C. Bianchet, Natalia Alves, Laura Zarraoa +2
We describe optical methods for trapping, cooling, and observing single Rb atoms in a four-lens "Maltese cross" geometry (MCG). The use of four high numerical-aperture lense…
