Two-setting Bell Inequalities for Graph States [PDF]
, 2005 We present Bell inequalities for graph states with high violation of local realism. In particular, we show that there is a two-setting Bell inequality for every nontrivial graph state which is violated by the state at least by a factor of two.

More randomness from noisy sources [PDF]
, 2014 Bell experiments can be used to generate private random numbers. An ideal Bell experiment would involve measuring a state of two maximally entangled qubits, but in practice any state produced is subject to noise.

Quantifying necessary quantum resources for nonlocality
Physical Review Research, 2022 Nonlocality is one of the most important resources for quantum information protocols. The observation of nonlocal correlations in a Bell experiment is the result of appropriately chosen measurements and quantum states.

Constructing multipartite Bell inequalities from stabilizers
Physical Review Research, 2022 Bell inequality with a self-testing property has played an important role in quantum information processing with both fundamental and practical significance.

SciPost Physics Core, 2023 It has recently been shown that by broadcasting the subsystems of a bipartite quantum state, one can activate Bell nonlocality and significantly improve noise tolerance bounds for device-independent entanglement certification.

Entangled-state cycles from conditional quantum evolution [PDF]
, 2006 A system of cascaded qubits interacting via the oneway exchange of photons is studied. While for general operating conditions the system evolves to a superposition of Bell states (a dark state) in the long-time limit, under a particular resonance ...

Bell’s Theorem for GeneralN-Qubit States [PDF]
Physical Review Letters, 2002 We derive a single general Bell inequality which is a necessary and sufficient condition for the correlation function for N particles to be describable in a local and realistic picture, for the case in which measurements on each particle can be chosen between two arbitrary dichotomic observables.

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