Measurements, Preparations, and Interpretations in Quantum Theory: A Comment on Meehan

I address the recent debate between Alexander Meehan and Lev Vaidman concerning the claim made by the former for a new problem to quantum mechanics. I argue that while Meehan’s incompatibility claim does hold in the situation he presents, it does not genuinely involve con-siderations that can limit quantum state preparation, nor does it introduce new constrains over possible interpretations of quantum theory.
