Observables have no value: a no-go theorem for position and momentum observables
arXiv:quant-ph/0603277 · doi:10.1007/s10701-007-9148-2
Abstract
A very simple illustration of the Bell-Kochen-Specker contradiction is presented using continuous observables in infinite dimensional Hilbert space. It is shown that the assumption of the \emph{existence} of putative values for position and momentum observables for one single particle is incompatible with quantum mechanics.
