Joint Distributions and Quantum Nonlocal Models
نویسندگان
چکیده
A standard result in quantum mechanics is this: if two observables are commuting then they have a classical joint distribution in every state. A converse is demonstrated here: If a classical joint distribution for the pair agrees with standard quantum facts, then the observables must commute. This has consequences for some historical and recent quantum nonlocal models: they are analytically disallowed without the need for experiment, as they imply that all local observables must commute among themselves.

Energetics of Protein Thermodynamic Cooperativity: Contributions of Local and Nonlocal Interactions
The respective roles of local and nonlocal interactions in the thermodynamic cooperativity of proteins are investigated using continuum (off-lattice) native-centric Gō-like models with a coarse-grained Ca chain representation. We study a series of models in which the (local) bondand torsion-angle terms have different strengths relative to the (nonlocal) pairwise contact energy terms. Conformati...
متن کاملQuantum probability assignment limited by relativistic causality
Quantum theory has nonlocal correlations, which bothered Einstein, but found to satisfy relativistic causality. Correlation for a shared quantum state manifests itself, in the standard quantum framework, by joint probability distributions that can be obtained by applying state reduction and probability assignment that is called Born rule. Quantum correlations, which show nonlocality when the sh...
متن کاملDistributions of the Ratios of Independent Kumaraswamy Variables and System Reliability Applications
In this article, first of all, the Kumaraswamy distribution is introduced. Then, the joint and marginal distributions of W = X1/X2 and T = X1/X1+X2 where X1 and X2 are independent Kumaraswamy random variables, are obtained and the moments of these random variables are computed. The distribution of random variables W and T can be used in reliability studies and statistical models...
متن کاملIs Bell’s theorem relevant to quantum mechanics? On locality and non-commuting observables
Bell’s theorem is a statement by which averages obtained from specific types of statistical distributions must conform to a family of inequalities. These models, in accordance with the EPR argument, provide for the simultaneous existence of quantum mechanically incompatible quantities. We first recall several contradictions arising between the assumption of a joint distribution for incompatible...
متن کاملHardy’s criterion of nonlocality for mixed states
We generalize Hardy’s proof of nonlocality to the case of bipartite mixed statistical operators, and we exhibit a necessary condition which has to be satisfied by any given mixed state σ in order that a local and realistic hidden variable model exists which accounts for the quantum mechanical predictions implied by σ. Failure of this condition will imply both the impossibility of any local expl...
