Detlef Dürr, Sheldon Goldstein and Nino Zanghì investigated how the usual quantum measurement rules arise in Bohmian mechanics, where a wave function guides a definite particle configuration. Their analysis connects quantum equilibrium, with configuration probability density , to the statistics of apparatus records. In this account, a self-adjoint operator summarizes a class of experimental procedures; its appearance does not require every quantum observable to be an additional pre-existing particle property.[ref]
