Genuine four-partite Bell nonlocality in the curved spacetime

European Physical Journal C: Particles and Fields
The quantum Bell nonlocality plays a crucial role in quantum information processing. In this paper, we first obtain the quantitative analytical expression of the genuine four-partite Bell nonlocality of any 4-qubit quantum state. Then, we investigate and

Maximally nonlocal Clauser-Horne-Shimony-Holt scenarios

Scientific Reports, 2018
The key feature in correlations established by multi-party quantum entangled states is nonlocality. A quantity to measure the average nonlocality, distinguishing it from shared randomness and in a direct relation with no-signaling stochastic processes ...

Influence of Nonlocality on Transmittance and Reflectance of Hyperbolic Metamaterials

Crystals, 2020
In this paper we investigate transmittance and reflectance spectra of multilayer hyperbolic metamaterials in the presence of strong spatial dispersion.

Nonlocality activation in a photonic quantum network

Nature Communications
Bell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocality is crucial for device-independent technologies like quantum key ...

Towards an equivalence between maximal entanglement and maximal quantum nonlocality

New Journal of Physics, 2018
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 nonlocality is poorly understood.

On the Non-Local Surface Plasmons’ Contribution to the Casimir Force between Graphene Sheets

Physics, 2020
Herein we demonstrate the dramatic effect of non-locality on the plasmons which contribute to the Casimir forces, with a graphene sandwich as a case study.

Nonlocal correlation in quantum network near a Schwarzschild black hole

European Physical Journal C: Particles and Fields
We transfer the scenario of quantum network nonlocal correlation to the vicinity of a black hole’s event horizon, aiming to evaluate the impact of Hawking effect on network nonlocality within this specific context.

Nonlocal effects in temporal metamaterials

Nanophotonics, 2022
Nonlocality is a fundamental concept in photonics. For instance, nonlocal wave-matter interactions in spatially modulated metamaterials enable novel effects, such as giant electromagnetic chirality, artificial magnetism, and negative refraction. Here, we
