Non-markovian quantum dynamics in strongly coupled multimode cavities conditioned on continuous measurement

V Link, K Müller, RG Lena, K Luoma, F Damanet… - PRX Quantum, 2022 - APS
An important challenge in non-Markovian open quantum systems is to understand what
information we gain from continuous measurement of an output field. For example, atoms in …
