Abstract

Given an ensemble of systems in an unknown state, as well as an observable A^\hat A and a physical apparatus which performs a measurement of A^\hat A on the ensemble, whose detailed working is unknown ('black box'), how can one test whether the L\"uders or von Neumann reduction rule applies?
