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...
Rational approximations to values of Bell polynomials at points involving Euler's constant and zeta values
Bell polynomials Euler's constant zeta values
2010/11/22
In this paper, we present new explicit simultaneous rational approximations converging sub-exponentially to the values of Bell polynomials at the points of the form $(\gamma, 1! (2a+1)\zeta(2), 2!\zet...
Bell diagonal states with maximal abelian symmetry

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...

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...
Parity proofs of the Bell-Kochen-Specker theorem based on the 600-cell
Parity proofs Bell-Kochen-Specker theorem based 600-cell
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 in Arbitrarily High-Dimensional Systems with Bell-Type Inequality
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...
Monogamy of multipartite Bell inequality violations
Monogamy multipartite Bell inequality violations
2010/11/4
We show that the complementarity relation between dichotomic observables leads to the monogamy of Bell inequality violations. We introduce a simple condition for the squares of expectation values of c...
Bell's Theory with no Locality assumption: putting Free Will at work
Bell's Theory Locality assumption putting Free at work
2010/10/29
We prove a version of the Bell's Theorem that does not assume Locality but only the Effect After Cause Principle (EACP) according to which for any Lorentz observer the value of an observable cannot ch...
We prove versions of the Bell and the GHZ Theorems that do not assume Locality but only the Effect After Cause Principle (EACP) according to which for any Lorentz observer the value of an observable c...
Detection Loophole in Bell experiments: How post-selected local correlations can look non-local
Detection Loophole Bell experiments non-local
2010/10/29
A common problem in Bell type experiments is the well-known detection loophole: if the detection efficiencies are not perfect and if one simply post-selects the conclusive events, one might observe a...
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...
Detection efficiency for loophole-free Bell experiments with postselection
Detection efficiency loophole-free Bell experiments postselection
2010/10/21
It is generally assumed that the violation of a Bell inequality by postselected events cannot be used for loophole-free tests of quantum nonlocality. We show that this is not the case if the postselec...
