Deterministic Underlying States are incompatible with a Counterfactual account of Lüders' rule

Alisson Tezzin, Bárbara Amaral, Jonte R. Hance

In this work, we show that a counterfactual account of L"uders' rule -- which we argue is naturally implied by the mathematical structure of the rule itself -- rules out underlying…
