Lifting Bell inequalities [PDF]
, 2005 A Bell inequality defined for a specific experimental configuration can always be extended to a situation involving more observers, measurement settings, or measurement outcomes. In this article, such "liftings" of Bell inequalities are studied.

British Educational Research Journal, EarlyView.Abstract Over the years, surveys and data on learning outcomes have consistently shown inadequate levels of learning in schools in India, witnessing a further decline in recent years. Studies within the sociology of education have consistently highlighted the overarching role of class and caste on learning outcomes in schools. Neoliberal policy reforms

, 2015 By calculating entanglement measures and quantum violation of Bell-type inequality, we reveal the relationship between entanglement measure and the amount of quantum violation for a family of four-qubit entangled states. It has been demonstrated that the

Chain of Hardy-type local reality constraints for $n$ qubits [PDF]
, 2010 Non-locality without inequality is an elegant argument introduced by L. Hardy for two qubit systems, and later generalised to $n$ qubits, to establish contradiction of quantum theory with local realism.

British Educational Research Journal, EarlyView.Abstract Drawing upon interview research across two academic departments as part of the early stages of a ‘decolonise the curriculum’ initiative at a Southern UK university, this study highlights a growing gulf between policy and practice in efforts to address systemic racial inequalities in UK universities. A reliance upon precarious labour, a culture

BELL'S INEQUALITIES DETECT EFFICIENT ENTANGLEMENT [PDF]
International Journal of Quantum Information, 2004 We review the status of Bell's inequalities in quantum information, stressing mainly the links with quantum key distribution and distillation of entanglement. We also prove that for all the eavesdropping attacks using one qubit, and for a family of attacks of two qubits, acting on half of a maximally entangled state of two qubits, the violation of a ...

Addressing racialised awarding gap in higher education: Insights from personal tutors
British Educational Research Journal, EarlyView.Abstract Situated within a wider cross‐institutional research project, this article provides an in‐depth case study of one higher education (HE) institution, focusing on how personal tutors make sense of racialised degree awarding disparities for both undergraduate and postgraduate students, how they perceive their responsibilities, the challenges and ...

Minimum detection efficiency for testing a multi-particle Bell inequality
New Journal of Physics, 2022 Bell’s inequality provides a remarkable way to test the consistency between quantum mechanics and classic local realistic theory. However, experimental demonstrations of the loophole-free Bell test are challenging and only recently have been demonstrated

Family of Bell inequalities violated by higher-dimensional bound entangled states [PDF]
, 2017 We construct ($d\times d$)-dimensional bound entangled states, which violate, for any $d>2$, a bipartite Bell inequality introduced in this paper. We conjecture that the proposed class of Bell inequalities acts as a dimension witness for bound entangled ...

Tests of Bell inequalities [PDF]
Physics Letters A, 2001 According to recent reports, the last loopholes in testing Bell's inequality are closed. It is argued that the really important task in this field has not been tackled yet and that the leading experiments claiming to close locality and detection efficiency loopholes, although making a very significant progress, have conceptual drawbacks.
