Nonlocal Interferometry - Beyond Bell’s Inequality

Conference on Coherence and Quantum Optics, 2007
This paper presents a tutorial review of nonlocal interferometry. The role of the Feynman propagator in optical coherence is also discussed, including the possibility of generating optical coherence and entanglement outside of the light cone.

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

Connector Tensor Networks: A Renormalization-Type Approach to Quantum Certification

Physical Review X, 2020
As quantum technologies develop, we acquire control of an ever-growing number of quantum systems. Unfortunately, current tools to detect relevant quantum properties of quantum states, such as entanglement and Bell nonlocality, suffer from severe ...

Effect of noise and enhancement of nonlocality in on/off photodetection [PDF]

, 2005
Nonlocality of two-mode states of light is addressed by means of CHSH inequality based on displaced on/off photodetection. Effects due to non-unit quantum efficiency and nonzero dark counts are taken into account.

Optimal measurements for nonlocal correlations

, 2016
A problem in quantum information theory is to find the experimental setup that maximizes the nonlocality of correlations with respect to some suitable measure such as the violation of Bell inequalities. The latter has however some drawbacks.

Interplay of quantum resources in nonlocality tests

Physical Review Research
Nonlocality, evidenced by the violation of Bell inequalities, not only signifies entanglement but also highlights measurement incompatibility in quantum systems.
