Characterizing entanglement of an artificial atom and a cavity cat state with Bell’s inequality
Characterizing entanglement cavity cat state Bell’s inequality
2016/1/22
The Schrodinger’s cat thought experiment highlights the counterintuitive concept of entan-glement in macroscopically distinguishable systems. The hallmark of entanglement is the detection of strong co...
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 ...
Interferometry with independent Bose-Einstein condensates: parity as an EPR/Bell quantum variable
Condensate quantum mechanical interferometer binary particles
2014/12/19
When independent Bose-Einstein condensates (BEC), described quantum mechanically by Fock (number) states, are sent into interferometers, the measurement of the output port at which the particles are d...
Bell's correlation for continuous local hidden causality is ambiguous
Bell inequalities classical probability EPR paradox General Physics
2012/4/24
In this letter it is demonstrated that Bell's correlation can be ambiguous for continuously distributed local hidden variables.
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...
Secure Quantum Communication and Superluminal Signalling on the Bell Channel
Bell Channel Quantum Communication and Superluminal Signalling
2011/9/1
A means and protocol is presented to send information on the Bell Channel to achieve the effect of superluminal signalling. The method is to use detection of a photon entangled state as one binary dig...
Photon Antibunching, Sub-Poisson Statistics and Cauchy-Bunyakovsky and Bell's Inequalities
Photon Antibunching Sub-Poisson Statistics Cauchy-Bunyakovsky Quantum Physics
2011/7/27
Abstract: We discuss some mathematical aspects of photon antibunching and sub-Poisson photon statistics. It is known that Bell's inequalities for entangled states can be reduced to the Cauchy-Bunyakov...
Bell diagonal states with maximal abelian symmetry
Bell diagonal maximal abelian symmetry Quantum Physics
2010/11/8
We provide a simple class of 2-qudit states for which one is able to formulate necessary and sufficient conditions for separability. As a byproduct we generalize well known construction provided by Ho...
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...
Note on "A note on "Loophole-free Bell test for continuous variables via wave and particle correlations""
A note on continuous variables via wave particle correlations
2010/11/9
In a recent note, Cavalcanti and Scarani (CS) constructed a counter local-hidden-variable model to explain the violation of our inequalities in Phys. Rev. Lett. 105, 170404 (2010). All such models ar...
A note on "Loophole-free Bell test for continuous variables via wave and particle correlations (Phys. Rev. Lett. 105, 170404 (2010))"
Loophole-free Bell test continuous variables via wave particle correlations
2010/11/8
The inequalities proposed in [Phys. Rev. Lett. 105, 170404 (2010)] are not Bell's inequalities in the usual sense: there are local classical models that violate these inequalities. Thus, their violati...
Loophole-free Bell test for continuous variables via wave and particle correlations
Loophole-free Bell test continuous variables via wave particle correlations
2010/11/8
We derive two classes of multi-mode Bell inequalities under local realistic assumptions, which are violated only by the entangled states negative under partial transposition in accordance with the Per...

2010/11/8
The set of 60 real rays in four dimensions derived from the vertices of a 600-cell is shown to possess numerous subsets of rays and bases that provide parity proofs of the Bell-Kochen-Specker (BKS) th...

Detecting Full N-Particle Entanglement Arbitrarily High-Dimensional Systems Bell-Type Inequality
2010/11/5
We derive a set of Bell-type inequalities for arbitrarily high-dimensional systems, based on the assumption of partial separability in the hybrid local-nonlocal hidden variable model. Partially entang...
