Quantum correlations on the no-signaling boundary: self-testing and more

In device-independent quantum information, correlations between local measurement outcomes observed by spatially separated parties in a Bell test play a fundamental role. Even though it is long-known

Bipartite polygon models: entanglement classes and their nonlocal behaviour

We study the bipartite composition of elementary toy systems with state spaces described by regular polygons. We provide a systematic method to characterize the entangled states in the maximal tensor

Self-testing quantum states via nonmaximal violation in Hardy's test of nonlocality

Self-testing protocols enable certification of quantum devices without demanding full knowledge about their inner workings. A typical approach in designing such protocols is based on observing

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

Hardy's nonlocality argument as a witness for postquantum correlations

Recently, Gallego et.al. [Phys. Rev. Lett 107, 210403 (2011)] proved that any future information principle aiming at distinguishing between quantum and post-quantum correlation must be intrinsically

Bound on Hardy's nonlocality from the principle of information causality

Recently, the principle of nonviolation of information causality [Nature 461, 1101 (2009)] has been proposed as one of the foundational properties of nature. We explore the Hardy's nonlocality

Device-Independent bounds for Hardy's experiment.

TLDR
An analogue of Tsirelson's bound for Hardy's test of nonlocality is computed, that is, the maximum violation of locality constraints allowed by the quantum formalism, irrespective of the dimension of the system.

Device- and semi–device-independent random numbers based on noninequality paradox

TLDR
This work proposes a new dimension witness paradox based on the Cabello's argument, which can be used for constructing semi-device-independent true random numbers generation protocol.

Constancy of maximal nonlocal probability in Hardy's nonlocality test for bipartite quantum systems

We give the generic form of the entangled states of a system of two spin-1 (and two spin-) particles and the appropriate set of spin observables that together exhibit maximum nonlocality under

Necessary and sufficient criterion for extremal quantum correlations in the simplest Bell scenario

In the study of quantum nonlocality, one obstacle is that the analytical criterion for identifying the boundaries between quantum and postquantum correlations has not yet been given, even in the

Local orthogonality provides a tight upper bound for Hardy's nonlocality

The amount of nonlocality in quantum theory is limited compared to that allowed in generalized no-signaling theory [Found. Phys. 24, 379 (1994)]. This feature, for example, gets manifested in the

Degree of Complementarity Determines the Nonlocality in Quantum Mechanics

Complementarity principle is one of the central concepts in quantum mechanics which restricts joint measurement for certain observables. Of course, later development shows that joint measurement
