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…
Quantum multiphase estimation
Marco Barbieri, Ilaria Gianani, Aaron Z. Goldberg +1
Quantum phase estimation is fundamental to advancing quantum science and technology. While much of the research has concentrated on estimating a single phase, the simultaneous esti…
Experimental protocol for qubit-environment entanglement detection
Gabriele Bizzarri, Linda Sansoni, Eleonora Stefanutti +4
Decoherence is a manifestation of the coupling of a system with its environment. The resulting loss of information can hamper the functioning of quantum devices, hence the need of…
