Recent numerical investigations [K. Pal and T. Vertesi, Phys. Rev. A 82, 022116 (2010)] suggest that the I3322 inequality, arguably the simplest extremal Bell inequality after the CHSH inequality, has a very rich structure in terms of the entangled states and measurements that maximally violate it. Here we show that for this inequality the maximally entangled state of any dimension achieves the same violation than just a single EPR pair. In contrast, stronger violations can be achieved using… 
The Essence of More Nonlocality with Less Entanglement in Bell Tests
In this paper, we will explore the essence of the phenomenon that state with less entanglement may generate greater Bell violation in the two-qubit Bell tests with CH-type inequalities, i.e., more
Measure of nonlocality which is maximal for maximally entangled qutrits
There is no doubt about the fact that entanglement and nonlocality are distinct resources. It is acknowledged that a clear illustration of this point is the difference between maximally entangled
Towards an equivalence between maximal entanglement and maximal quantum nonlocality
While all bipartite pure entangled states are known to generate correlations violating a Bell inequality, and are therefore nonlocal, the quantitative relation between pure-state entanglement and
Maximum nonlocality in the (3,2,2) scenario
We identify the simplest combinations of entanglement and incompatibility giving the maximum quantum violation for each of the 46 classes of tight Bell inequalities for the (3,2,2) scenario, i.e.,
Measure-independent anomaly of nonlocality
We show that any Bell local state, with a hidden nonlocality that can be revealed by local filtering, is more, or equally, entangled than nonlocal states. More precisely, it can be deterministically
More nonlocality with less entanglement in Clauser-Horne-Shimony-Holt experiments using inefficient detectors
It is shown that the CHSH Inequality can always be violated for any nonzero detection efficiency and any choice of non-commuting measurements.
Bell scenarios in which nonlocality and entanglement are inversely related
We show that for two-qubit chained Bell inequalities with an arbitrary number of measurement settings, nonlocality and entanglement are not only different properties but are inversely related.
Tripartite realism-based quantum nonlocality
From an operational criterion of physical reality, a quantifier of realism-based nonlocality was recently introduced for two-part quantum states. This measure has shown to capture aspects that are
Nonanomalous measure of realism-based nonlocality
Based on a recently proposed model of physical reality and an underlying criterion of nonlocality for contexts [A. L. O. Bilobran and R. M. Angelo, Europhys. Lett. {\bf 112}, 40005 (2015)], we
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


Quantum nonlocality in two three-level systems
Recently a new Bell inequality has been introduced (CGLMP,KKCZO) that is strongly resistant to noise for maximally entangled states of two d-dimensional quantum systems. We prove that a larger
Large Violation of Bell Inequalities with Low Entanglement
In this paper we obtain violations of general bipartite Bell inequalities of order $${\frac{\sqrt{n}}{\log n}}$$ with n inputs, n outputs and n-dimensional Hilbert spaces. Moreover, we construct
An anomaly of non-locality
This work reviews the present knowledge on this anomaly, points out that Hardy's theorem has the same feature, and discusses the perspectives opened by these discoveries.
Semi-device-independent bounds on entanglement
It is shown that Bell-type inequalities are not only useful in verifying the presence of entanglement but can also be used to bound theEntanglement of the underlying physical system.
Entanglement and non-locality are different resources
Bell's theorem states that, to simulate the correlations created by measurement on pure entangled quantum states, shared randomness is not enough: some 'non-local' resources are required. It has been
Maximal violation of the Collins-Gisin-Linden-Massar-Popescu inequality for infinite dimensional states.
For very large values of d the inequality seems to reach its minimal value given by the probability constraints, which gives numerical evidence for a tight quantum Bell inequality (or generalized Csirelson inequality) for the 2x2xinfinity scenario.
A relevant two qubit Bell inequality inequivalent to the CHSH inequality
We computationally investigate the complete polytope of Bell inequalities for two particles with small numbers of possible measurements and outcomes. Our approach is limited by Pitowsky's connection
Consequences and limits of nonlocal strategies
This paper investigates various aspects of the nonlocal effects that can arise when entangled quantum information is shared between two parties, and establishes limits on nonlocal behavior by upper-bounding the values of several of these games.
Optimal bell tests do not require maximally entangled states.
Numerical results show that the required optimal state does not have to be maximally entangled, and the maximization over states and measurements defines the optimal nonlocality proof.
Extremal quantum correlations for N parties with two dichotomic observables per site
Consider a scenario where $N$ separated quantum systems are measured, each with one among two possible dichotomic observables. Assume that the $N$ events corresponding to the choice and performance
