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…
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…
