Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

In 1960, the mathematician Ernst Specker described a simple example of nonclassical
correlations, the counter-intuitive features of which he dramatized using a parable about a …

Two central concepts of quantum mechanics are Heisenberg's uncertainty principle and a
subtle form of nonlocality that Einstein famously called “spooky action at a distance.” These …

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 …

Nonlocality is the most characteristic feature of quantum mechanics, but recent research
seems to suggest the possible existence of nonlocal correlations stronger than those …

In recent years, the use of information principles to understand quantum correlations has
been very successful. Unfortunately, all principles considered so far have a bipartite …

Quantum theory is not only successfully tested in laboratories every day but also constitutes
a robust theoretical framework: small variations usually lead to implausible consequences …

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 …

It is a relatively new insight of classical statistics that empirical data can contain information
about causation rather than mere correlation. First algorithms have been proposed that are …

We take a resource-theoretic approach to the problem of quantifying nonclassicality in Bell
scenarios. The resources are conceptualized as probabilistic processes from the setting …
