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…

Joint estimation of position and momentum with arbitrarily high precision using non-Gaussian states
Massimo Frigerio, Matteo G. A. Paris, Carlos Ernesto Lopetegui +1
We address the joint estimation of changes in the position and linear momentum of a quantum particle or, equivalently, changes in the complex field of a bosonic mode. Although thes…
