Quantum parameter estimation using general single-mode Gaussian states

Pinel, Olivier; Jian, Pu; Treps, Nicolas; Fabre, Claude; Braun, D

Description

We calculate the quantum Cramér-Rao bound for the sensitivity with which one or several parameters, encoded in a general single-mode Gaussian state, can be estimated. This includes in particular the interesting case of mixed Gaussian states. We apply the
