A decision-theoretic approach to dealing with uncertainty in quantum mechanics

ArXi:2503.20607v3 Announce Type: replace-cross We provide a decision-theoretic framework for dealing with uncertainty in quantum mechanics. This uncertainty is two-fold: on the one hand there may be uncertainty about the state the quantum system is in, and on the other hand, as is essential to quantum mechanical uncertainty, even if the quantum state is known, measurements may still produce an uncertain outcome. In our framework, measurements. therefore.
