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

The Impact of Traineeships on the Employment of the Mentally Ill: the Role of Partial Compliance

Lavoro&Psiche is a RCT aimed at increasing employment among severely mentally ill patients, by offering them a structured job-search experience. The key feature of the treatment was the presence of a “job coach” entirely dedicated to support the job search of a small number (12-13) of mentally ill patients. What most often the job coach did was finding the patient a traineeship. If one were to consider only the effect of making the support of the coach available - the so-called Intention-To-Treat effect – it would be a disappointing statistically non significant 5 percentage point difference in the employment of treatment and control members, in the full post-treatment year. However, the impact of making something available is rarely the primary interest of policy-makers, who would rather know the effect of receiving it. The main difficulty in obtaining unbiased estimates of the latter is that ‘who receives what’ is no longer solely determined by randomization, but also by post-randomization events and decisions. During the implementation period of Lavoro&Psiche of 2011-12, an unprecedented wave of traineeship opportunities hit those enrolled in the demonstration, both in the experimental and in the control group. The main finding is that, for the subset of the experimental group that was induced by the offer to be involved in a traineeship the chances of having a job in the post-treatment year more than double from the 17% of those who did not do any traineeship to the 34% of those who did, well above the Intention-To-Treat impact estimates
