“…Similarly in quantum phenomena which we observe and create there should be something behind the scenes which is causally responsible for outcomes we register. In our opinion quantum probabilities neither correspond to irreducible propensities of individual physical systems nor to beliefs of some human agents but they are objective properties of quantum phenomena as a whole [4,5,31,37,67,68,70]. Necessity of probabilistic description is due to the lack of control on what is going behind the scenes.…”

Eighty years ago Einstein, Podolsky and Rosen demonstrated that the instantaneous reduction of wave function, believed to describe completely a pair of entangled physical systems, led to EPR paradox. The paradox disappears in statistical interpretation of quantum mechanics (QM) according to which a wave function describes only an ensemble of identically prepared physical systems. QM predicts strong correlations between the outcomes of measurements performed on different members of EPR pairs in far-away locations. Searching for an intuitive explanation of these correlations John Bell analysed so called local realistic hidden variable models and proved that these models always satisfy Bell inequalities which are violated by the predictions of QM and by experimental data. Several different local models were constructed and inequalities proven. Some eminent physicists concluded that Nature is definitely nonlocal and that it is acting according a new law of nonlocal randomness. According to this law perfectly random, but strongly correlated events, can be produced at the same time at far away locations and a spatio-temporal, local and causal explanation of their occurrence cannot be given. We strongly disagree with this conclusion and in this paper we criticise various finite sample proofs of Bell and CHSH inequalities and so called Quantum Randi Challenges. We also show how one can win so called Bell's game without violating locality of Nature. Nonlocal randomness is inconsistent with local quantum field theory, with standard model in elementary particle physics and with causal laws and adaptive dynamics prevailing in the surrounding us world. The experimental violation of Bell-type inequalities does not prove the nonlocality of Nature but it only confirms the contextual character of quantum observables and gives a strong argument against the point of view according to which the experimental outcomes are produced in irreducible random way. In spite of the fact that we have no doubt that Bell type inequalities are violated we show that because the homogeneity of samples was not tested carefully enough the significance of violation cannot be trusted.

A research program within the scope of theories on "Emergent Quantum Mechanics" is presented, which has gained some momentum in recent years. Via the modeling of a quantum system as a non-equilibrium steady-state maintained by a permanent throughput of energy from the zero-point vacuum, the quantum is considered as an emergent system. We implement a specific "bouncerwalker" model in the context of an assumed sub-quantum statistical physics, in analogy to the results of experiments by Couder's group on a classical wave-particle duality. We can thus give an explanation of various quantum mechanical features and results on the basis of a "21 st century classical physics", such as the appearance of Planck's constant, the Schrödinger equation, etc. An essential result is given by the proof that averaged particle trajectories' behaviors correspond to a specific type of anomalous diffusion termed "ballistic" diffusion on a sub-quantum level.It is further demonstrated both analytically and with the aid of computer simulations that our model provides explanations for various quantum effects such as double-slit or n-slit interference.We show the averaged trajectories emerging from our model to be identical to Bohmian trajectories, albeit without the need to invoke complex wave functions or any other quantum mechanical tool. Finally, the model provides new insights into the origins of entanglement, and, in particular, into the phenomenon of a "systemic" nonlocality.

“…The authors show within the Heisenberg picture that the opening or closing of a slit results in the nonlocal transfer of (what they call "modular") momentum. (Our group has shown that this effect can also be demonstrated when using the Schrödinger picture [15]. )…”

We understand emergent quantum mechanics in the sense that quantum mechanics describes processes of physical emergence relating an assumed sub-quantum physics to macroscopic boundary conditions. The latter can be shown to entail top-down causation, in addition to usual bottom-up scenarios. With this example it is demonstrated that definitions of "realism" in the literature are simply too restrictive. A prevailing manner to define realism in quantum mechanics is in terms of pre-determination independent of the measurement. With our counter-example, which actually is ubiquitous in emergent, or self-organizing, systems, we argue for realism without pre-determination.We refer to earlier results of our group showing how the guiding equation of the de Broglie-Bohm interpretation can be derived from a theory with classical ingredients only. Essentially, this corresponds to a "quantum mechanics without wave functions" in ordinary 3-space, albeit with nonlocal correlations. This, then, leads to the central question of how to deal with the nonlocality problem in a relativistic setting. We here show that a basic argument discussing the allegedly paradox time ordering of events in EPR-type two-particle experiments falls short of taking into account the contextuality of the experimental setup. Consequently, we then discuss under which circumstances (i.e. physical premises) superluminal information transfer (but not signaling) may be compatible with a Lorentzinvariant theory. Finally, we argue that the impossibility of superluminal signaling -despite the presence of superluminal information transfer -is not the result of some sort of conspiracy (á la "Nature likes to hide"), but the consequence of the impossibility to exactly reproduce in repeated experimental runs a state's preparation, or of the no-cloning theorem, respectively.The term "Emergent Quantum Mechanics" (EmQM) has been used in the literature for several years by now, albeit with different meanings regarding the word "emergence". As a major option, the term refers to the possibility that quantum theory might be a (very good) approximation to some "deeper level theory". To some, though, EmQM just stands for quantum theory as a special case for a particular set of parameters of a more encompassing theory. The term would thus refer to the emergence of a theory. However, the meaning of EmQM may also be more specific in that it refers to physical emergence, i.e., to the modeling of quantum systems as emergent systems. It is the latter option that our group has dealt with throughout the last couple of years.There is, however, a communication problem in getting the relevant ideas across, mainly because the quantum physics and the self-organization/emergence communities, respectively, hardly communicate with each other. Specifically, the problem of accepting physical emergence as a possibility within the quantum physics community seems to be the rather exotic looking theme of top-down causation (next to bottom-up causation). Despite the fact that there are numerous exampl...
