Quantum metrology in the presence of correlated noise via Markovian embedding
Arpan Das, RafaÅ Demkowicz-DobrzaÅski
We analyze quantum metrological protocols, where the sensing system is linearly coupled to a bosonic environment, by performing a Markovian embedding of the problem based on pseudo…

Universal time scalings of sensitivity in Markovian quantum metrology
Arpan Das, Wojciech Gorecki, Rafal Demkowicz-Dobrzanski
Assuming Markovian time evolution of a quantum sensing system, we study the general characterization of the optimal sensitivity scalings with time, under most general quantum contr…
