Author(s): A. De Pasquale, D. Rossini, P. Facchi, and V. Giovannetti We provide a general framework for handling the effects of a unitary disturbance on the estimation of the amplitude λ associated to a unitary dynamics. By computing an analytical and general expression for the quantum Fisher information, we prove that the optimal estimation precision for λ cannot be... [Phys. Rev.
