Optimal phase estimation in the presence of correlated dephasing
Srijon Ghosh, Arkadiusz Kobus, Stanisław Kurdziałek +1
We investigate optimal metrological protocols for phase estimation in the presence of correlated dephasing noise, including spin-squeezed states sensing strategies as well as paral…
Adaptive quantum channel discrimination using methods of quantum metrology

Quantum metrology in the presence of correlated noise via Markovian embedding
Arpan Das, Rafał Demkowicz-Dobrzański
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…
Asymptotically optimal joint phase and dephasing strength estimation using spin-squeezed states
Arkadiusz Kobus, Rafał Demkowicz-Dobrzański
We show an explicit -qubit protocol involving one-axis-twisted spin squeezed states, that allows for simultaneous phase and dephasing strength estimation with precision that asy…
