The Violation of Bell Inequalities in the Macroworld
Diederik Aerts Sven Aerts Jan Broekaert and Liane Gabora
2015/7/31
We show that Bell inequalities can be violated in the macroscopic world. The macroworld violation is
illustrated using an example involving connected vessels of water. We show that whether the violat...
EPR argument and Bell inequalities for Bose-Einstein spin condensates
Condensate spin state quantum mechanical particles
2014/12/19
We discuss the properties of two Bose-Einstein condensates in different spin states, represented quantum mechanically by a double Fock state. Individual measurements of the spins of the particles are ...
A complete set of multidimensional Bell inequalities
multidimensional Bell inequalities Quantum Physics
2011/9/30
Abstract: We give a multidimensional generalisation of the complete set of Bell-correlation inequalities given by Werner and Wolf for the two-dimensional case. Our construction applies for the n parti...
Quantum Bell Inequalities from Macroscopic Locality
Macroscopic Locality Bell Inequalities Quantum Physics
2010/11/8
We propose a method to generate analytical quantum Bell inequalities based on the principle of Macroscopic Locality. By imposing locality over binary processings of virtual macroscopic intensities, we...
Non-adaptive Measurement-based Quantum Computation and Multi-party Bell Inequalities
Non-adaptive Measurement-based Quantum Computation Multi-party Bell Inequalities
2010/10/21
Quantum correlations exhibit behaviour that cannot be resolved with a local hidden variable picture of the world. In quantum information, they are also used as resources for information processing tas...
Temporal Leggett-Garg-Bell inequalities for sequential multi-time actions in quantum information processing, and a re-definition of Macroscopic Realism
Temporal Leggett-Garg-Bell inequalities sequential multi-time actions quantum information processing a re-definition Macroscopic Realism
2010/10/19
The usual formulation of Macrorealism is recast to make this notion fully concurrent with the basic ideas behind classical physics. The assumption of non-invasiveness of measurements is dropped. Inste...
Extended Boole-Bell inequalities applicable to quantum theory
Boole inequalities Bell inequalities quantum theory EPR paradox
2010/4/8
We address the basic meaning of apparent contradictions of quantum theory and probability frameworks as expressed by Bell's inequalities. We show that these contradictions have their origin in the inc...
The relevance of random choice in tests of Bell inequalities with atomic qubits
random choice tests Bell inequalities atomic qubits
2010/4/7
It is pointed out that a loophole exists in experimental tests of Bell inequality using atomic qubits, due to possible errors in the rotation angles of the atomic states. A sufficient condition is der...
Quantum Correlations in Inflationary Spectra and Violation of Bell Inequalities
Quantum Correlations Inflationary Spectra Violation of Bell Inequalities
2010/10/18
In spite of the macroscopic character of the fluctuation amplitudes, we show that the standard inflationary distribution of primordial density fluctuations still exhibits inherently quantum mechanical...
Orbital Entanglement and Violation of Bell Inequalities in the Presence of Dephasing
orbital entanglement dephasing Bell Inequalities mesoscopic physics
2010/4/12
We discuss orbital entanglement in mesoscopic conductors, focusing on the effect of dephasing. The entanglement is detected via violation of a Bell Inequality formulated in terms of zero-frequency cur...
