Quantum Nonlocality and Beyond: Limits from Nonlocal Computation [PDF]
We address the problem of "nonlocal computation," in which separated parties must compute a function without any individual learning anything about the inputs. Surprisingly, entanglement provides no benefit over local classical strategies for such tasks, yet stronger nonlocal correlations allow perfect success.

Causal hierarchy of multipartite Bell nonlocality [PDF]
As with entanglement, different forms of Bell nonlocality arise in the multipartite scenario. These can be defined in terms of relaxations of the causal assumptions in local hidden-variable theories.

General Non-Markovian Quantum Dynamics
A general approach to the construction of non-Markovian quantum theory is proposed. Non-Markovian equations for quantum observables and states are suggested by using general fractional calculus.

Einstein-Podolsky-Rosen Steering for Mixed Entangled Coherent States
By using the Born Markovian master equation, we study the relationship among the Einstein–Podolsky–Rosen (EPR) steering, Bell nonlocality, and quantum entanglement of entangled coherent states (ECSs) under decoherence.

Simultaneous sudden change in the exact values of geometric quantum discord and measurement induced nonlocality [PDF]
Recent studies show that two completely distinct fields as quantum information and string theory realization can be related and share some of the same properties.

Decoherence-Induced Sudden Death of Entanglement and Bell Nonlocality
Decoherence due to the unwanted interaction between a quantum system and environment leads to the degradation of quantum coherence. In particular, for an entangled state, decoherence makes a loss of entanglement and Bell nonlocality known as entanglement

Mediated digraphs and quantum nonlocality
A digraph D=(V,A) is mediated if, for each pair x,y of distinct vertices of D, either xy belongs to A or yx belongs to A or there is a vertex z such that both xz,yz belong to A. For a digraph D, DELTA(D) is the maximum in-degree of a vertex in D. The "nth mediation number" mu(n) is the minimum of DELTA(D) over all mediated digraphs on n vertices ...

Discriminating quantum correlations with networking quantum teleportation
The Bell inequality, and its substantial experimental violation, offers a seminal paradigm for showing that the world is not in fact locally realistic.

Exploring the Limits of Quantum Nonlocality with Entangled Photons
Nonlocality is arguably among the most counterintuitive phenomena predicted by quantum theory. In recent years, the development of an abstract theory of nonlocality has brought a much deeper understanding of the subject, revealing a rich and complex ...
