Nonlocality, No-Signalling and Bell's Theorem investigated by Weyl's Conformal Differential Geometry
The principles and methods of the Conformal Quantum Geometrodynamics (CQG)
based on the Weyl's differential geometry are presented. The theory applied to
the case of the relativistic single quantum spin 1/2 leads a novel and
unconventional derivation of Dirac's equation. The further extension of the
theory to the case of two spins 1/2 in EPR entangled state and to the related
violation of Bell's inequalities leads, by an exact albeit non relativistic
analysis, to an insightful resolution of all paradoxes implied by quantum
nonlocality.Comment: arXiv admin note: text overlap with arXiv:1203.003
Experimental Realization of Polarization Qutrits from Non-Maximally Entangled States
Based on a recent proposal [Phys. Rev. A 71, 062337 (2005)], we have
experimentally realized two photon polarization qutrits by using non-maximally
entangled states and linear optical transformations. By this technique high
fidelity mutually unbiased qutrits are generated at a high brilliance level.Comment: RevTex, 8 pages, 6 figure
Realization and characterization of a 2-photon 4-qubit linear cluster state
We report on the experimental realization of a 4-qubit linear cluster state
via two photons entangled both in polarization and linear momentum. This state
was investigated by performing tomographic measurements and by evaluating an
entanglement witness. By use of this state we carried out a novel nonlocality
proof, the so-called ``stronger two observer all versus nothing'' test of
quantum nonlocality.Comment: 4 pages, 4 figure
