On the role of symmetry and geometry in global quantum sensing
Julia Boeyens, Jonas Glatthard, Edward Gandar +3
Global quantum sensing enables parameter estimation across arbitrary ranges with a finite number of measurements. Among the various existing formulations, the Bayesian paradigm sta…

Controlling the spontaneous emission of trapped ions
Tommaso Faorlin, Benjamin Yadin, Yannick Weiser +7
We propose an experimental setup for manipulating the spontaneous emission of trapped ions, based on a spatial light modulator. Anticipated novelties include the potential to entan…

How exchange symmetry impacts performance of collective quantum heat engines
Julia Boeyens, Benjamin Yadin, Stefan Nimmrichter
Recently, multilevel collectively coupled quantum machines like heat engines and refrigerators have been shown to admit performance enhancements in analogy to superradiance. Thus f…
