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…
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…
Probe thermometry with continuous measurements
Julia Boeyens, Björn Annby-Andersson, Pharnam Bakhshinezhad +5
Temperature estimation plays a vital role across natural sciences. A standard approach is provided by probe thermometry, where a probe is brought into contact with the sample and e…
Uninformed Bayesian Quantum Thermometry
Julia Boeyens, Stella Seah, Stefan Nimmrichter
We study the Bayesian approach to thermometry with no prior knowledge about the expected temperature scale, through the example of energy measurements on fully or partially thermal…
Zero-energy quasiparticles in an interacting nanowire containing a topological Josephson junction
Julia Boeyens, Izak Snyman
We study a Josephson junction in a Kitaev chain with particle-hole symmetric nearest neighbor interactions. When the phase difference across the junction is , we show analytical…
