Lorentz-Invariant "Elements of Reality" and the Question of Joint Measurability of Commuting Observables
Abstract
It is shown that the joint measurements of some physical variables corresponding to commuting operators performed on pre- and post-selected quantum systems invariably disturb each other. The significance of this result for recent proofs of the impossibility of realistic Lorentz invariant interpretation of quantum theory (without assumption of locality) is discussed.
