Semiparametric estimation in Hong-Ou-Mandel interferometry
Valeria Cimini, Francesco Albarelli, Ilaria Gianani +1
We apply the theory of semiparametric estimation to a Hong-Ou-Mandel interference experiment with a spectrally entangled two-photon state generated by spontaneous parametric downco…
Kramers-Kronig relations and precision limits in quantum phase estimation
Ilaria Gianani, Marco Barbieri, Francesco Albarelli +3
The ultimate precision in any measurement is dictated by the physical process implementing the observation. The methods of quantum metrology have now succeeded in establishing boun…
Quantum asymmetry and noisy multi-mode interferometry
Francesco Albarelli, Mateusz Mazelanik, Michał Lipka +3
Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator responsible for phase encoding in interferometric exper…
Probe incompatibility in multiparameter noisy quantum metrology
Francesco Albarelli, Rafal Demkowicz-Dobrzanski
We derive fundamental bounds on the maximal achievable precision in multiparameter noisy quantum metrology, valid under the most general entanglement-assisted adaptive strategy, wh…
