Bayesian stepwise estimation of qubit rotations
Mylenne Manrique, Marco Barbieri, Assunta Di Vizio +4
This work investigates Bayesian stepwise estimation (Se) for measuring the two parameters of a unitary qubit rotation. While asymptotic analysis predicts a precision advantage for…
Controlling Sloppiness in Two-Phase Estimation with a Tunable Weak Measurement
Gabriele Bizzarri, Miranda Parisi, Mylenne Manrique +6
The description of complex systems requires a progressively larger number of parameters. However, in practice, it often happens that a small subset of parameters suffices to descri…
Photon-starved polarimetry via functional classical shadows
Matteo Rosati, Miranda Parisi, Linda Sansoni +3
Polarimetry and optical imaging techniques face challenges in photon-starved scenarios, where the low number of detected photons imposes a trade-off between image resolution, integ…
Faithful and secure distributed quantum sensing under general-coherent attacks
G. Bizzarri, M. Barbieri, M. Manrique +4
Quantum metrology and cryptography can be combined in a distributed and/or remote sensing setting, where distant end-users with limited quantum capabilities can employ quantum stat…
