Gaussian quantum estimation of the lossy parameter in a thermal environment
Robert Jonsson, Roberto Di Candia
Lossy bosonic channels play an important role in a number of quantum information tasks, since they well approximate thermal dissipation in an experiment. Here, we characterize thei…

Non-perturbative treatment of giant atoms using chain transformations
David D. Noachtar, Johannes Knörzer, Robert H. Jonsson
Superconducting circuits coupled to acoustic waveguides have extended the range of phenomena that can be experimentally studied using tools from quantum optics. In particular giant…
