In this paper we introduce a measure of genuine quantum incompatibility in the estimation task multiple parameters, that has geometric character and is backed by clear operational interpretation. This then applied to some simple systems order track effect local depolarizing noise on task. A semidefinite program described used numerically compute figure merit when analytical tools are not suffic...

the problem of estimating the parameter ?, when it is restricted to an interval of the form , in a class of discrete distributions, including binomial negative binomial discrete weibull and etc., is considered. we give necessary and sufficient conditions for which the bayes estimator of with respect to a two points boundary supported prior is minimax under squared log error loss function. for s...
