Fisher informations and local asymptotic normality for continuous-time quantum Markov processes
Catalin Catana, Luc Bouten, Madalin Guta
We consider the problem of estimating an arbitrary dynamical parameter of an quantum open system in the input-output formalism. For irreducible Markov processes, we show that in th…
Heisenberg versus standard scaling in quantum metrology with Markov generated states and monitored environment
Catalin Catana, Madalin Guta
Finding optimal and noise robust probe states is a key problem in quantum metrology. In this paper we propose Markov dynamics as a possible mechanism for generating such states, an…
Maximum likelihood versus likelihood-free quantum system identification in the atom maser
Catalin Catana, Theodore Kypraios, Madalin Guta
We consider the system identification problem of estimating a dynamical parameter of a Markovian quantum open system (the atom maser), by performing continuous time measurements in…
Asymptotic inference in system identification for the atom maser
Catalin Catana, Merlijn van Horssen, Madalin Guta
System identification is an integrant part of control theory and plays an increasing role in quantum engineering. In the quantum set-up, system identification is usually equated to…
