On the discontinuity of the quantum Fisher information for quantum statistical models with parameter dependent rank
Luigi Seveso, Francesco Albarelli, Marco G. Genoni +1
We address the discontinuities of the quantum Fisher information (QFI) that may arise when the parameter of interest takes values that change the rank of the quantum statistical mo…

Daniele Bonalda, Luigi Seveso, Matteo G. A. Paris
We address the problem of sensing the curvature of a manifold by performing measurements on a particle constrained to the manifold itself. In particular, we consider situations whe…
