Testing Bell inequalities in Higgs boson decays
Physics Letters B, 2022 Higgs boson decays produce pairs of W bosons in a maximally entangled state, the spins of which can be expected to violate Bell inequalities. We show that the spin density matrix of the W± pair may be reconstructed experimentally from the directions of ...

The Platonic solids and fundamental tests of quantum mechanics [PDF]
Quantum, 2020 The Platonic solids is the name traditionally given to the five regular convex polyhedra, namely the tetrahedron, the octahedron, the cube, the icosahedron and the dodecahedron.

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.

LOCALITY AND BELL'S INEQUALITY [PDF]
Foundations of Probability and Physics, 2001 We prove that the locality condition is irrelevant to Bell in equality. We check that the real origin of the Bell's inequality is the assumption of applicability of classical (Kolmogorovian) probability theory to quantum mechanics. We describe the chameleon effect which allows to construct an experiment realizing a local, realistic, classical ...

Does a large quantum Fisher information imply Bell correlations?
, 2019 The quantum Fisher information (QFI) of certain multipartite entangled quantum states is larger than what is reachable by separable states, providing a metrological advantage.

Local vertical measurements and violation of Bell inequality [PDF]
, 2007 For two qubits belonging to Alice and Bob, we derive an approach to setup the bound of Bell operator in the condition that Alice and Bob continue to perform local vertical measurements.

Study of Free‐Space Optical Quantum Network: Review and Prospectives
Advanced Science, EarlyView.Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

, 2012 Quantum theory allows for correlations between the outcomes of distant measurements that are inconsistent with any locally causal theory, as demonstrated by the violation of a Bell inequality.

Australian Journal of Social Issues, EarlyView.ABSTRACT Over almost two decades, young people's employment opportunities have been significantly impacted by events like the Global Financial Crisis (2008–2009) and the COVID‐19 pandemic (2020‐). Thus, underemployment has become a more pervasive and persistent feature of young people's labour market experiences. This research focuses on three forms of

Open Physics, 2017 Bell’s stated assumptions in deriving his inequality were sufficient conditions. It is shown that a far simpler condition exists for derivation of the inequality: the mere existence of finite data sets regardless of their statistical or deterministic ...
