Multipartite Entanglement Detection Via Projective Tensor Norms

- Computer ScienceAnnales Henri Poincaré
- 2022

This work introduces and study a class of entanglement criteria based on the idea of applying local contractions to an input multipartite state, and then computing the projective tensor norm of the output, which allows for systematic relations between the performance of these two criteria.

Quantum communication complexity advantage implies violation of a Bell inequality

- PhysicsProceedings of the National Academy of Sciences
- 2016

It is proved that any large advantage over the best known classical strategy makes use of Bell nonlocal correlations, providing the missing link to the fundamental equivalence between Bell nonlocality and quantum advantage.

Restriction on the local realism violation in three-qubit states and its relation with tripartite entanglement

- PhysicsScientific Reports
- 2018

This work describes the states which give the extremal quantum values of a Bell-type inequality for a given value of the tripartite entanglement and shows that such extremal states can be reached if one introduced an appropriate order induced by the three-πEntanglement measure.

On the existence of a local quasi hidden variable (LqHV) model for each N-qudit state and the maximal quantum violation of Bell inequalities

- Mathematics

We specify the local quasi hidden variable (LqHV) model reproducing the probabilistic description of all N-partite joint von Neumann measurements on an N-qudit state. Via this local probability…

New concise upper bounds on quantum violation of general multipartite Bell inequalities

- Computer Science
- 2016

The LqHV mathematical framework allows us to derive for all d and N a new upper bound on the maximal violation by an N-qudit state of all general Bell inequalities, and for some S, d, and N, the new upper bounds are attainable.

Quantum bounds on multiplayer linear games and device-independent witness of genuine tripartite entanglement

- Computer Science
- 2016

A systematic method is presented to derive device-independent witnesses of genuine tripartite entanglement, and to show in a simple manner that any nontrivial functional box, that could lead to trivialization of communication complexity in a multiparty scenario, cannot be realized in quantum mechanics.

Random Constructions in Bell Inequalities: A Survey

- Physics
- 2015

The aim of the present work is to review some of the recent results in this direction by focusing on the main ideas and removing most of the technical details, to make the previous study more accessible to a wide audience.

Multipartite entanglement in XOR games

- MathematicsQuantum Inf. Comput.
- 2013

It is shown that the multipartite entangled states that are most often seen in today's literature can only lead to a bias that is a constant factor larger than the classical bias, which has the following surprising consequence: classical three-player XOR games do not follow an XOR parallel repetition theorem, even a very weak one.

Quantum steerability: Characterization, quantification, superactivation, and unbounded amplification

- Physics
- 2016

Quantum steering, also called Einstein-Podolsky-Rosen steering, is the intriguing phenomenon associated with the ability of spatially separated observers to steer---by means of local…

More nonlocality with less entanglement in Clauser-Horne-Shimony-Holt experiments using inefficient detectors

- Computer SciencePhysical Review A
- 2018

It is shown that the CHSH Inequality can always be violated for any nonzero detection efficiency and any choice of non-commuting measurements.

We prove that there are tripartite quantum states (constructed from random unitaries) that can lead to arbitrarily large violations of Bell inequalities for dichotomic observables. As a consequence…

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,…

We consider one-round games between a classical verifier and two provers who share entanglement. We show that when the constraints enforced by the verifier are ‘unique’ constraints (i.e.,…

In this Letter we show that quantum nonlocality can be superactivated. That is, one can obtain violations of Bell inequalities by tensorizing a local state with itself. In the second part of this…
