Quantum coherence and the bell inequality violation: a numerical experiment with the cavity QEDs
Frontiers in PhysicsBell inequality violation has been widely tested by using the bipartite entangled pure states and properly encoding the local observables in various experimental platforms, and the detector-, local-, and random loopholes have already been closed.

Beating no-go theorems by engineering defects in quantum spin models
New Journal of Physics, 2015 Diverse no-go theorems exist, ranging from no-cloning to monogamies of quantum correlations and Bell inequality violations, which restrict the processing of information in the quantum world.

Unitary transformations for testing Bell inequalities
, 2001 It is shown that optical experimental tests of Bell inequality violations can be described by SU(1,1) transformations of the vacuum state, followed by photon coincidence detections. The set of all possible tests are described by various SU(1,1) subgroups

Quantum-collapse Bell inequalities [PDF]
Physical Review A, 2014 We propose Bell inequalities for discrete or continuous quantum systems which test the compatibility of quantum physics with an interpretation in terms of deterministic hidden-variable theories. The wave function collapse that occurs in a sequence of quantum measurements enters the upper bound via the concept of quantum conditional probabilities.

British Educational Research Journal, EarlyView.Abstract This paper explores the growing influence of young people's activism in UK museums and its educational implications. It draws on a five‐year collaborative programme (2019–2023) with young people of colour (16–28) in a university museum setting, focusing on a Young Collective established to address cultural inequalities.

Bell correlations at finite temperature [PDF]
Quantum, 2018 We show that spin systems with infinite-range interactions can violate at thermal equilibrium a multipartite Bell inequality, up to a finite critical temperature $T_c$.

The European Physical Journal Special Topics, 2021 Quantum non-locality tests have been of interest since the 1960's paper by Bell on the original EPR paradox.The present paper discusses whether the CGLMP (Bell) inequalities are possible tests for showing that quantum theory is not underpinned by local hidden variable theory (LHVT).

Bell Inequalities with Auxiliary Communication [PDF]
Physical Review Letters, 2003 What is the communication cost of simulating the correlations produced by quantum theory? We generalize Bell inequalities to the setting of local realistic theories augmented by a fixed amount of classical communication. Suppose two parties choose one of M two-outcome measurements and exchange 1 bit of information.

The future in a bubble: Supporting Finnish early childhood professionals working in diverse settings
British Educational Research Journal, EarlyView.Abstract The purpose of this study was to contribute to the knowledge about early childhood education and care (ECEC) personnel's perception of the support structures that are most effective in assisting them in their work with culturally and linguistically diverse children.
