Randomness versus nonlocality in the Mermin-Bell experiment with three parties [PDF]

open access: yesQuantum, 2018
The detection of nonlocal correlations in a Bell experiment implies almost by definition some intrinsic randomness in the measurement outcomes. For given correlations, or for a given Bell violation, the amount of randomness predicted by quantum physics ...

Deletion, Bell’s inequality, teleportation [PDF]

open access: yesQuantum Information Processing, 2010
In this letter we analyze the efficacy of the entangled output of Pati-Braunstein deletion machine [3] as a teleportation channel. We analyze the possibility of it violating the Bell's inequality. Interestingly we find that for all values of the input parameter$ $ the state does not violate the Bell's inequality but when used as a teleportation ...

Measurement Incompatibility versus Bell Nonlocality: An Approach via Tensor Norms

open access: yesPRX Quantum, 2022
Measurement incompatibility and quantum nonlocality are two key features of quantum theory. Violations of Bell inequalities require quantum entanglement and incompatibility of the measurements used by the two parties involved in the protocol.

Violation of Bell-CHSH Inequalities through Optimal Local Filters in the Vacuum

open access: yesQuantum Reports, 2020
We investigate quantum correlations appearing for two-qubit detectors which are initially uncorrelated and locally coupled to a massless scalar field in a vacuum state.

Maximal nonlocality from maximal entanglement and mutually unbiased bases, and self-testing of two-qutrit quantum systems [PDF]

open access: yesQuantum, 2019
Bell inequalities are an important tool in device-independent quantum information processing because their violation can serve as a certificate of relevant quantum properties. Probably the best known example of a Bell inequality is due to Clauser, Horne,

Violation of all two-party facet Bell inequalities by almost-quantum correlations

open access: yesPhysical Review Research, 2021
The characterization of the set of quantum correlations is a problem of fundamental importance in quantum information. The question whether every proper (tight) Bell inequality is violated in quantum theory is an intriguing one in this regard.

Does violation of a Bell inequality always imply quantum advantage in a communication complexity problem? [PDF]

open access: yesQuantum, 2020
Quantum correlations which violate a Bell inequality are presumed to power better-than-classical protocols for solving communication complexity problems (CCPs). How general is this statement?
