Einstein–Podolsky–Rosen–Bohm experiments: A discrete data driven approach

Vacuum Correlations, Detector Efficiency Fluctuations and Classical Dynamic Violations of CH-Inequality

“…that, looks like the familiar thermodynamic second law, implies an oscillatory decay regime towards an equilibrium value, if the detector has temperature wave oscillations. We note that an interesting thermodynamic interpretation of Bell inequality violations can be suggested if we substitute to the entropy the opposite of the correlation function S. In fact the correlation function decay implied by (37),during the experimental run of Bell tests can be conceived as a kind of vacuum entropy growth associated to vacuum correlations induced by photodetection and, contrary to the standard approach, not caused by entangled photon pairs generated by a laser source We remark that this approach might be applied to reformulate a very interesting proposal of generalized C.H.S.H inequalities published this year [11] 4 2 S ≤ − ∆ (38) once we suppose the ∆ term of the previous formula, and therefore the different experimental set up quadruples, to be dependent on the fluctuating detector index ∆n, introduced in (23); in this way the previous inequality can be shown to be equivalent with a similar inequality obtained by the author [9] having the same upper and lower bounds ( )…”

“…Notwithstanding the very definite claims contained in this paper on the realization of loophole free Bell tests and their conclusion on the impossibility to complete Quantum Mechanics by local deterministic models there are still a lot of authors that disagree with these opinions [8] [9] [10] [11] [12] [13]. In particular these papers are considered to have proved the statistical point of view of the Copenhagen interpretation against the followers of classical models, as Einstein and Debroglie.…”

“…We will try in this paper to show with a deterministic local model how to bypass Bell like inequalities, discussing a new loophole, which we call "vacuum correlation loophole", which is present, as far as we know, in every free loophole E.P.R.-Bell like experiments. Over more in the last two years have appeared some papers which generalize C.H.S.H inequalities [9] [11] which pave the way to future definite experimental disproval of Bell theorem with experiments realized with classical electromagnetic fields or hydrodynamic waves, as recently showed [14] [15] [16].…”

“…We remark that our proposal deviates from a recent similar objection to Bell like tests (13) since we interpret the photon count probability in the integrand as a byproduct of vacuum induced signal fluctuations generated during the measurement process (which is usually interpreted as background thermal noise). We reformulate the (11), taking in account (10), making it dependent on the contextual hidden variable given by the fluctuating detector efficiency…”

Quantum Nonlocality: How Does Nature Do It?

“…Therefore, the violation of Bell–CHSH inequalities does not allow for far reaching metaphysical speculations. Let us cite here Hans de Raedt et al [ 57 ]: “all EPRB experiments which have been performed and may be performed in the future and which only focus on demonstrating a violation BI-CHSH merely provide evidence that not all contributions to the correlations can be reshuffled to form quadruples… These violations do not provide a clue about the nature of the physical processes that produce the data… ” Similar conclusions may be found in [ 6 , 44 , 45 , 58 , 59 , 60 , 61 , 62 ].…”
