چکیده

We report on the realisation of a new test of Bell inequalities using the superposition of type I parametric down conversion produced in two different non-linear crystals pumped by the same laser, but with different polarisations. We discuss the advantages and the possible developments of this configuration. Many experiments have already been devoted to a test of Bell inequalities [1–5], leading to a substantial agreement with quantum mechanics and disfavouring realistic local hidden * [email protected].

A new conception experimental test of Bell inequalities using non - maximally entangled states

We report on a test of Bell inequalities using a non-maximally entangled state, which represents an important step in the direction of eliminating the detection loophole. The experiment is based on the creation of a polarisation entangled state via the superposition, by use of an appropriate optics, of the spontaneous fluorescence emitted by two non-linear crystals driven by the same pumping la...

Bell Inequalities in High Energy Physics

We review in this paper the research status on testing the completeness of Quantum mechanics in High Energy Physics, especially on the Bell Inequalities. We briefly introduce the basic idea of Einstein, Podolsky, and Rosen paradox and the results obtained in photon experiments. In the tests of Bell inequalities in high energy physics, the early attempts of using spin correlations in particle de...

Strict hierarchy among Bell Theorems

As demonstrated by John Bell, quantum mechanics exhibits correlations in spacelike separated bipartite systems that are impossible to reproduce by classical means. There are three levels of “Bell Theorems”, depending on which aspects of the quantum correlations can or cannot be reproduced classically. The original “Bell Inequalities” (BI) require a perfect classical simulation of all quantum pr...

Ii. Nonlocality without Inequalities for Hardy States

Hardy’s proof of “nonlocality without inequalities” [1] provides the simplest demonstration of Bell’s theorem [2] that there is no local realistic theory reproducing all predictions of quantum mechanics. Curiously, while the maximum violation of Bell inequalities occurs for maximally entangled states [3], Hardy’s proof does not go through for maximally entangled states. Recently, Wu, Xie, Huang...

Experimental violation of a spin-1 bell inequality using maximally entangled four-photon states.

We demonstrate the experimental violation of a spin-1 Bell inequality. The spin-1 inequality is based on the Clauser, Horne, Shimony, and Holt formalism. For entangled spin-1 particles, the maximum quantum-mechanical prediction is 2.55 as opposed to a maximum of 2, predicted using local hidden variables. We obtained an experimental value of 2.27+/-0.02 using the four-photon state generated by p...
