Physical origin of quantum nonlocality and contextuality

  title={Physical origin of quantum nonlocality and contextuality},
  author={Ad{\'a}n Cabello},
We prove that in a universe in which there are no laws governing the outcomes of some measurements and in which, as a consequence, every behavior that is not forbidden in a physical theory does take place, the sets of behaviors for Bell and Kochen-Specker-contextuality scenarios are identical to those allowed in quantum theory. This suggests that the physical principle that singles out which forms of Bell nonlocality and Kochen-Specker-contextuality are allowed in nature is simply the…

The measurement postulates of quantum mechanics are operationally redundant

The mathematical structure of quantum measurements and the Born rule are usually imposed as axioms; the authors show instead that they are the only possible measurement postulates, if the authors require that arbitrary partitioning of systems does not change the theory’s predictions.

Quantum Randomness is Chimeric

This work presents a brief review of the metaphysics of indeterminism, and examines the emergence of both space-time as well as the identification of physical properties through which so-called objects are aggregated.

Deriving Born’s Rule from an Inference to the Best Explanation

This article discusses further how to obtain (or rather infer) Born’s rule within this framework, where the structure of quantum mechanics appears as a result of the interplay between the quantized number of modalities accessible to a quantum system and the continuum of contexts that are required to define these modalities.

Spurious, Emergent Laws in Number Worlds

We study some aspects of the emergence of lógos from xáos on a basal model of the universe using methods and techniques from algorithmic information and Ramsey theories. Thereby an intrinsic and

Series Spurious , Emergent Laws in Number Worlds

We study some aspects of the emergence of lógos from xáos on a basal model of the universe using methods and techniques from algorithmic information and Ramsey theories. Thereby an intrinsic and

Faithful orthogonal representations of graphs from partition logics

Two immediate consequences are the demonstration that the logico-empirical structure of observables does not determine the type of probabilities alone and that complementarity does not imply contextuality.



Locality, Bell's theorem, and quantum mechanics

Classical relativistic physics assumes that spatially separated events cannot influence one another (“locality”) and that values may be assigned to quantities independently of whether or not they are

Two Fundamental Experimental Tests of Nonclassicality with Qutrits

In classical physics, there is no contradiction in considering that systems like balls and coins have preestablished properties like position and velocity that are independent of whether one actually

Quantum Mechanics in the Light of Quantum Cosmology

We sketch a quantum mechanical framework for the universe as a whole. Within that framework we propose a program for describing the ultimate origin in quantum cosmology of the quasiclassical domain

Bell Nonlocality

Nonlocality was discovered by John Bell in 1964, in the context of the debates about quantum theory, but is a phenomenon that can be studied in its own right. Its observation proves that measurements

Experimental observation of Hardy-like quantum contextuality.

This work experimentally observes the arguably cleanest form of contextuality in quantum theory by implementing a novel method for performing two sequential measurements on heralded photons and opens the door to a variety of fundamental experiments and applications.

Quantum correlations are tightly bound by the exclusivity principle.

This work provides a tight constraint inequality imposed by this principle and proves that this principle singles out quantum correlations in scenarios represented by any graph, implying that the exclusivity principle might be one of the fundamental principles of nature.

Quantum nonlocality and beyond: limits from nonlocal computation.

This work addresses the problem of "nonlocal computation," in which separated parties must compute a function without any individual learning anything about the inputs, and provides intriguing insights into the limits of quantum information processing, the nature of quantum nonlocality, and the differences between quantum and stronger-than-quantum nonlocal correlations.

Implausible consequences of superstrong nonlocality

It is shown that the existence of maximally superstrong correlated bits implies that all distributed computations can be performed with a trivial amount of communication, i.e. with one bit.

A glance beyond the quantum model

One of the most important problems in physics is to reconcile quantum mechanics with general relativity, and some authors have suggested that this may be realized at the expense of having to drop the

Experimental non-classicality of an indivisible quantum system

An experiment with single photonic qutrits provides evidence that no joint probability distribution describing the outcomes of all possible measurements—and, therefore, no non-contextual theory—can exist.
