In the previous section we derived an exact expression for two-mode Gaussian states, however, in recent work [ 14] a general formula for the quantum Fisher information was derived as a limit of a particular infinite series. Here we simplify the expression for the infinite series.
WebThe Fisher information matrix formalism allows a quick and easy way to estimate errors on cosmological parameters, given errors in observable quantities, and is particularly useful in experimental design. The Fisher matrix is defined as the (negative) Hessian of the log-likelihood function , WebFeb 4, 2016 · Recent works on the Fisher matrix extend the formalism also to errors in the independent variables (Heavens et al. 2014) and to non-Gaussianity (Joachimi & Taylor 2011; Sellentin, Quartin & Amendola 2014; Sellentin 2015). Its ease of handling can be traced back to many analytical operations that can be performed on a multivariate …
