Under a standard set of assumptions for a hidden-variable model for quantum events we show that all observables must commute simultaneously. This seems to be an ultimate statement about the inapplicability of the usual hidden-variable model for quantum events. And, despite Bell's complaint that a key condition of von Neumann's was quite unrealistic, we show that these conditions, under which von Neumann produced the first no-go proof, are entirely equivalent to those introduced by Bell and… 
Comment on “All quantum observables in a hidden-variable model must commute simultaneously”
Malley discussed [Phys. Rev. A 69, 022118 (2004)] that all quantum observables in a hidden-variable model for quantum events must commute simultaneously. In this comment, we discuss that Malley's
Classical Probability and Quantum Outcomes
TLDR
An essential task here is a closer identification of this conflict based on deriving commutativity from the weakest possible assumptions, and showing that stronger assumptions in some of the existing no-go proofs are unnecessary.
Noncommuting observables and local realism
Local realism does not impose the commutative algebraic structure into all quantum observables
Malley and Fine (Phys. Rev. A 2006 73 066102) discussed that all quantum observables would commute simultaneously if we accept a realistic theory of the Bell type (a local realistic theory) for
Logical Difficulty from Combining Counterfactuals in the GHZ-Bell Theorems
In eliminating the fair sampling assumption, the Greenberger, Horne, Zeilinger (GHZ) theorem is believed to confirm Bell’s historic conclusion that local hidden variables are inconsistent with the
A principle of quantumness
Quantum correlations and other phenomena characteristic to a quantum world can be understood as simply consequences of a principle derived from the postulates of Quantum Mechanics. This explanatory
Quantum-collapse Bell inequalities
Department of Physics and Astronomy, University of Manitoba, Winnipeg, Manitoba R3T 2N2, CanadaWe propose Bell inequalities for discrete or continuous quantum systems which test the compati-bility of
Quasi-Bell inequalities from symmetrized products of noncommuting qubit observables
Noncommuting observables cannot be simultaneously measured, however, under local hidden variable models, they must simultaneously hold premeasurement values, implying the existence of a joint
Excluding joint probabilities from quantum theory
Quantum theory does not provide a unique definition for the joint probability of two non-commuting observables, which is the next important question after the Born's probability for a single
Quantum Cryptographic Security from Contextuality Gelo
TLDR
Device-independent security from contextuality is demonstrated by considering a distributed box of Peres-Mermin observables for the Kochen Specker theorem and the security of the corresponding key distribution protocol is certified by checking for not-too-strong violations of Bell inequalities.
