Protecting Heisenberg scaling in quantum metrology via engineered dressed states
Wojciech Gorecki, Christiane P. Koch
Quantum metrology promises precision beyond classical limits but environmental noise, unless properly controlled, reduces the quantum advantage to at most a constant improvement. A…

Interplay between time and energy in bosonic noisy quantum metrology
Wojciech Górecki, Francesco Albarelli, Simone Felicetti +2
Quantum entanglement and coherence often allow for protocols that outperform classical ones in estimating a system's parameter. When using infinite-dimensional probes (such as a bo…

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…
