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…

Probing atom-surface interactions from tunneling-time measurements via rotation-transport on an atom chip

J-B. Gerent, R. Veyron, V. Mancois +3

We propose a novel method to measure the interaction between an ultracold gas of neutral atoms and a surface. This solution combines an optical dipole trap reflected by the surface…

Distinguishing synthetic unravelings on quantum computers

Eloy Piñol, Piotr Sierant, Dustin Keys +6

Distinct monitoring or intervention schemes can produce different conditioned stochastic quantum trajectories while sharing the same unconditional (ensemble-averaged) dynamics. Thi…

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…

All-optical bubble trap for ultracold atoms in microgravity

Romain Veyron, Clément Métayer, Jean-Baptiste Gérent +5

In this paper, we present an all-optical method to produce shell-shaped traps for ultracold atoms in microgravity. Our scheme exploits optical double dressing of the ground state t…

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…

Telling different unravelings apart via nonlinear quantum-trajectory averages

Eloy Piñol, Th. K. Mavrogordatos, Dustin Keys +7

The Gorini-Kossakowski-Sudarshan-Lindblad master equation (ME) governs the density matrix of open quantum systems (OQSs). When an OQS is subjected to weak continuous measurement, i…

In situ subwavelength microscopy of ultracold atoms using dressed excited states

Romain Veyron, Jean-Baptiste Gérent, Guillaume Baclet +3

In this work, we implement a new method for imaging ultracold atoms with subwavelength resolution capabilities and determine its regime of validity. It uses the laser driven intera…

Quantitative absorption imaging of optically dense effective two-level systems

Romain Veyron, Vincent Mancois, Jean-Baptiste Gerent +3

Absorption imaging is a commonly adopted method to acquire, with high temporal resolution, spatial information on a partially transparent object. It relies on the interference betw…

Effective two-level approximation of a multi-level system driven by coherent and incoherent fields

Romain Veyron, Vincent Mancois, Jean-Baptiste Gerent +3

The numerical simulation of multiple scattering in dense ensembles is the mostly adopted solution to predict their complex optical response. While the scalar and vectorial light me…
