Abstract
The theory of Quantum Mechanics is one of the mainstay of modern physics, a well-established mathematical clockwork whose strength and accuracy in predictions are currently experienced in worldwide research laboratories. As a matter of fact, Quantum Mechanics laid the groundwork of a rich variety of studies ranging from solid state physics to cosmology, from bio-physics to particle physics. The up-to-date ability of manipulating single quantum states is paving the way for emergent quantum technologies as quantum information and computation, quantum communication, quantum metrology and quantum imaging. In spite of the impressive matemathical capacity, a long-standing debate is even revolving around the foundational axioms of this theory, the main bones of content being the non-local effects of entangled states, the wave function collapse and the concept of measurement in Quantum Mechanics, the macro-objectivation problem (the transition from a microscopic probabilistic world to a macroscopic deterministic world described by classical mechanics). Problems that, beyond their fundamental interest in basic science, now also concern the impact of these developing technologies. Without claiming to be complete, this article provides in outline the living matter concerning some of these problems, the implications of which extend deeply on the connection between entanglement and space-time structure.

Summary
EPJ Web of Conferences separation has been unequivocally achieved [14, 15] and more recently detection loophole [16, 17] has been eliminated [18,19,20], a conclusive test is still missing [1] since the two conditions were not realised at the same time, even if not significant chances remain for LHVT. These achievements fostered the interest for quantum non-locality and, more in general, for quantum correlations. In the following we present some recent progresses in studying quantum non-locality and related hypothesis of Bell’s theorem
