Nonlocality without nonlocality∗
Bell’s theorem is purported to demonstrate the impossibility of a nonlocal “hidden variable” theory underpinning quantum mechanics. It relies on the well-known assumption of ‘locality’, and also on a little-examined assumption called ‘statistical independence’ (SI). Violations of this assumption have variously been thought to suggest “backward causation”, a “conspiracy” on the part of nature, o...
متن کاملApparent nonlocality
Syntactic processes and dependencies are normally restricted to certain domains. * This phenomenon of locality has been a central object of study for decades, and it is still relevant in the Minimalist Program, especially in connection with the idea of phases/cycles. A standard example is provided in (1), where the underscore indicates the regular surface position of the extracted whphrase, the...
متن کاملDistilling nonlocality.
Two parts of an entangled quantum state can have a correlation, in their joint behavior under measurements, that is unexplainable by shared classical information. Such correlations are called nonlocal and have proven to be an interesting resource for information processing. Since nonlocal correlations are more useful if they are stronger, it is natural to ask whether weak nonlocality can be amp...
متن کاملNonlocality in Kinetic Roughening
“Suppose that we take a bin and gently and uniformly pour in granular material. As the material in the bin builds up we can identify a surface and ask the question, ‘What is the magnitude of the fluctuation in the height of surface (measured from the base of the bin)?’ Also of interest is the length scale of the surface fluctuations and how they behave dynamically as more material is added” [1]...
متن کاملQuantifying multipartite nonlocality.
The nonlocal correlations of multipartite entangled states can be reproduced by a classical model if sufficiently many parties join together or if sufficiently many parties broadcast their measurement inputs. The maximal number m of groups and the minimal number k of broadcasting parties that allow for the reproduction of a given set of correlations quantify their multipartite nonlocal content....
