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…

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…
