Typicality of Heisenberg scaling precision in multi-mode quantum metrology

Published: Mar 27, 2020
Abstract
We propose a measurement setup reaching Heisenberg scaling precision for the estimation of any distributed parameter \varphi(not necessarily a phase) encoded into a generic Mport linear network composed only of passive elements. The scheme proposed can be easily implemented from an experimental point of view since it employs only Gaussian states and Gaussian measurements. Due to the complete generality of the estimation problem considered,...
