Asymptotically optimal joint phase and dephasing strength estimation using spin-squeezed states
Arkadiusz Kobus, RafaÅ Demkowicz-DobrzaÅski, 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…

Optimal phase estimation in the presence of correlated dephasing
Srijon Ghosh, Arkadiusz Kobus, StanisÅaw KurdziaÅek +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…
